REALLY narks me. most of you are talking about a totally different thing. if someone makes a fab coleslaw, asking them to make one, 'would you mind, because everyone loves yours' is a totally different thing.
we had mil's 80th on sat. was lovely. as soon as i heard months ago, i rang the appropraite sil ( there are 6 of them !!) and as ususal asked what she would like me to do. all brothers, sils' always do the same. we had bbq. so much meat. salads. sil2 was in charge of deserts etc etc. god they throw a fab friggin party do my dh's family.
but, as an alternative, on the first england match, we were invited to a bbq by friends of ours. they live in a huge house and, well i'm sorry, they are lovely, but very very tight. they earn a fortune and parents are rich. they asked us to bring all food, all drinks and everything we would need. dh phoned and asked her dh what exactly it was that he was contributing. he said, we're hosting. really, asked dh .
when we throw parties. we throw parties. hog roasts. coleslaws . salads. lay on loads of booze. but all our friends bring loads and loads with them also. tons of booze, wine etc etc. now THATS the way to do it.
so Op, YANBU. they are tight as arses
