I guess you could say I'm an introverted extrovert. Or an extroverted introvert. I spend a lot of time in my head and got used to not sharing whats in there. I quite enjoy silence and privacy while also enjoying company and a louder ambiance(not that the two are exclusive to each other).
I can be quite reserved upon first contact, preferring to observe rather than interact, unless of course I feel comfortable around you. It depends on a host of factors. Sometimes I just don't feel like talking much, other times you can't get me to shut up. If you're looking for something longer term you're going to have to be ok with that.
I dislike small talk or forced chat. Its empty and boring as far as I'm concerned. I prefer to have proper, deeper discussions about anything really. I'm usually not content to just keep it at the surface so generally I will take the conversation deeper.
I do better one-on-one or in small groups than I do with large crowds or groups of people.
Once you do get past my initial caution I can be quite silly/goofy. I can laugh at a fair range of humours. I tend to be absurd, wordy(punny) or sarcastic(I also enjoy irony quite a bit).
