Hi ALAJ
This was an interesting blog post I read last year - it's about Thanksgiving but I think many of the ideas in it are useful for any occasion and can be adapted.
Crying Out Now: Thanksgiving Survival Guide
I've found myself much less 'social' since I got sober - I actually don't enjoy mingling with strangers very much but I've accepted that's the 'real' me.
I'm civil and polite but I'm not the life of the party - and that's ok with me now
