Personality: Upon first meeting Lithuania, most will see him as a shy, polite kind of guy whom they can sense they'll get along with. He looks plain, not threatening, average at best on all levels at first glance. He's a nice guy and easy to mesh with, and though Lithuania is a bit on the introverted side, he's quite popular in his own right, just because people tend to have a fondness for him. He's not quick to anger and mild-mannered in most situations. Do him wrong? He'll be hurt, of course, but your transgressions will be forgiven in his own way, though it may take a while (though probably not). That's not to say he forgives and forgets, however. He carries a lot of memories with him; it's hard not to when you're a country. He might not always say he forgives someone, but the relationship of whoever has troubled him will resume to normal quite quickly, such as with Poland and his aggravation towards him that normally lasted no more than a minute or two. Lithuania tends to look for the best in people and he's blind to a lot of faults, whether by density or just selective realization, or both. He's not necessarily trusting, though, and he's been done wrong a few too many times to just let his guard down so easily. He chooses who he's comfortable with, and it shows. He's polite and congenial, more apt to be formal with acquaintances. When Lithuania is with people he's closer to, or at least more familiar with or used to, there's an obvious air about him that exudes a bit more familiarity and that he's more relaxed.

Concerning his emotions, Lithuania may be easy to read, but he keeps most of his emotions on the inside, not really openly admitting to a lot of the feelings he has. Normally it's plainly obvious how he feels, at least to more perceptive individuals, but he never out-rightly states how he feels and internalizes a lot of his worries and concerns, but only when it comes to himself. He'll continuously fret and fluster about something, enough to cause him great stress and probably an ulcer or two; he doesn't want pity or anyone to dote on him in times of need. More than anything, he wants to be independent. He's got it all under control. It all comes with being a country; he has a strong sense of independence and the ability to do things himself. Lithuania is a private person, unwilling to share the hardships he's faced, not even his best friend.

A bundle of nerves, Lithuania is always thinking about something. When living with Russia during WWII, he constantly worried over whether Poland was going to get invaded, whether Poland was ready for battle, whether Poland had any kind of defense. It's shown that he worries about his own safety, Poland's well-being, his brothers' (Estonia and Latvia) safety (though their relationship is a little lop-sided; Estonia and Latvia seem to hold him in higher regard than how he sees them, though he does have feelings of concern for them), and even how America is doing. He's nervous in general and is like a mom and housewife rolled into one, always concerned about the general state of those close to him, enough to take a lot of loads onto his own shoulders.

He likes to take care of those he cherishes too, unafraid of taking on more than his share of the work, though it's something he doesn't necessarily choose for himself sometimes, and he might complain about it a little along the way. He does find enjoyment and fulfillment in it, though, as seen with taking care of the laid back America after World War I. When forced to do things he doesn’t like or agree with, such as doing Russia’s bidding or being subjected to one too many of Poland’s whims, he doesn’t enjoy himself nearly as much. Lithuania is also kind of indebted to and knows a lot of countries, what with being moved around a lot and having to have a little assistance to stay afloat. Once, upon seeing Japan, he thanked him profusely and was very congenial towards him, all because Japan supported him a little during a tough time, though the gesture wasn't reciprocated. Though he likes to try to stay within the bounds of his close friends and brothers, he's a decent guy who likes those who help him and works well with them.

With all that concern and worry comes a bad spell or two. Though Lithuania is resilient, he's by no means optimistic. He knows that he’s still alive and now that he’s self reliant, it’ll all be okay in the end...maybe. His pessimism isn't true pessimism, just that he knows (based on his history), that bad stuff happens and he needs to be prepared for things. Lithuania's constantly got something heavy on his mind, and with people like Poland and Russia in his life, he's going to have a freak out occasionally. These range from annoyance to downright panicking, depending on how far he's pushed and the severity of the issue. He deals with a lot of stress, strain, and has had a hard time coping in the past, so he’s a little on edge, and one can’t really blame him. It's taken a toll on his body as well, and it's known that Lithuania has his fare share of stomach problems and "colds" (aka the economy isn't doing so hot). It's hard for him to be comfortable somewhere right off the bat. Since he was young, he's stayed close to only a select few people, namely Poland and his Baltic brothers, Estonia, Latvia, and Belarus (though that’s certainly debatable on her part). Though he's capable of getting close to others, he'd rather be with one of them than anywhere else and won't necessarily go out of his way to make friends, no matter how personable he seems. As a side note, it's important to know that Lithuania has only gotten really, legitimately angry once, arguably twice. It wasn't directly said to the aggressor in question, and he recovered quickly. His fuse is long and only a spark when it does finally light.
