My family and I are very close. We're an international family, so we're not geographically close, but that hardly matters. On the flip side, I won't require sharing when it comes to holidays, my family is generally unavailable. It's also huge - when we do get together we rent out towns... Locally, friends become my surrogate family.
I enjoy new things; I like to order items off the menu I haven't tried yet, explore new hobbies, strike up different conversation, flash a smile and say Hi to a stranger. At least once a day, I try to stray from my comfort zone, do something that I'd normally elect not to do.
In the last couple of years, I've more or less swung my personality from that of a cynic to an optimist, which has definitely impacted who I tend to be around more, personality wise.
