Well this all depends on your situation, my relatives tend to spend their time complaining and judging and that is a toxic atmosphere to be spending time around for any more then an hour or so. The older generation tend to be rigid and cynical as they express their opinions in their own narrow minded worlds, and i dont mean that to be offensive but it's just what i notice. I find alot of the older generation aka (uncles, aunties, parents, grand parents) often arn't very open minded and like to feed off of gossip and negativity, grumpiness etc...and sure they do try and make some fun as well.
I think If I spent christmas around younger people my age then at least it would be more relaxed and fun that way.
Maybe its just people who complain and judge, gossip that really irk me at family gatherings, and if they look at me while in the midst of a gossipy speal i tend to look away without acknowledging them because i really don't want to be agreeing or expressing an opinion on something i have no grounds of knowledge about, if they look at me for approval then i'll avoid joining in on their prejudices because i tend to be more open minded and understanding about people and their issues where as i find alot of people are not open minded or sympathetic and like to step on people behind their backs through gossip. no thanks, i just want to sit there and talk about something fun and relaxing where a conversation can really flow through just talking about non-people specific related topics like music, movies, work, etc ...
