I'm just sort of awkward and uncomfortable with any group of people, period. Regarding family, it's less so with distant relatives, as I'm not expected to talk to them at all at large family gatherings. I'm fine with immediate relatives, as, well, I've lived with them for most of my life. It's when I'm interacting with the "in-betweeners" that the situation becomes viscerally awkward and I start looking for an escape route. They're close enough to approach me, awkwardly try to hug me and half-heartedly ask about school and work, but not close enough to care what my response is, instead asking out of a sense of "you're my family, so I'm supposed to be interested in your life." I dread family gatherings for this reason. It's obvious that no one actually gives a shit, but you still feel compelled to participate in the "How's school? Oooh, that's great." song and dance. I was relieved when I was finally old enough to decide for myself if and when I would attend family parties.
