Man, I know those feels. When I go to family dinners what goes through my head is just don't make eye contact, don't make eye contact. I usually just plant myself on the floor with my 3 year old cousin and play dinosaur. That, or I'm the one that's running around with a camera to shove in people's faces, if it's an event that needs have printable memories anyway (gran's 80th birthday, my cousin's graduation).
And I'm not out yet either.
I figure, that once I come out (or my mum shares the news for me, as it'll probably end up being) it'll be real awkward and my first impulse will be to hide away for a bit. However, thinking about it, that'll probably just make things even more awkward. From my perspective anyway. Personally, I think the way I'll end up going is trying to see them in small doses, either a couple of people at a time for game night or maybe a brief appearance at the New Year's party my mum's siblings always have together.
You know, I feel there'll probably be a couple of congrats thrown my way, if they are accepting, which they probably will be, maybe a question or two, but as long as something else is the focus point, I think the awkwardness of it all will cease pretty quickly. Needless to say, I won't be throwing a coming out party to invite my family to.
Bottom line is, it's nothing to be ashamed of. I think my beef with it is really just the drawing attention to myself part, I like it when they just sort of forget that I'm there, probably something I aquired from living abroad for such a huge chunk of my life, didn't have to see them all the time. I understand the awkwardness of it all though.
