Ended up saying I'll go to my uncle's 50yr old party next weekend.. but I'm not a fan of this uncle at all! Bit of backstory with the whole thing really involving cazy religious types and a very unhappy christmas do...after which i said to my aunt i didn't think i could go to a family gathering of that nature again - which she forwarded to my whole family?!
So she was very keen fo me to come along to this, and i guess it'd be good for my extended family to see 3month old DS.. but really on a personal level i'm just in it for the food. Now feeling guilty as you can probably tell!
