I'm not all that particular about what I do if I'm spending time with friends; it's the shared time/experiences that matter most to me--I'm a "quality time" kinda guy. I'm happy to roadtrip with friends, sit around a table and chat or play games, or whatever sounds good to us at the time.
I tend to have a rather reserved sense of humour; a bit dry and punny. Tennant's Doctor sarcastically asking "are you my mummy?" made me laugh out loud last week as I continue my tear through Doctor Who on Netflix. Allons-y!
I listen to all sorts of music; mostly my music selection varies by mood. I enjoy instrumental tracks, and this week have a new playlist mixing Doctor Who, Dark Knight, Star Wars, Gladiator, Anastasia, Aladdin, Lion King, and Star Trek pieces.
I'm a furry-pet person; I grew up with two cats, and as such consider myself to be a 'cat person'. I've tended to enjoy the company of dogs that belong to friends, but have never belonged to one myself.
On the whole, I tend to be on the quiet side, especially when I don't know people all that well. The larger the group, the quieter I tend to be on the outside. Once I know people, I tend to surprise them.
Regardless of the setting, I often find that I think a lot faster than I can speak, and have been known to make seemingly random leaps of logic in what I say, even though there's actually a discernible path from one thing to the other in my head.
