My mum did and I do mostly. If I have people round for a buffet, things like quiche and sausage rolls, cake are homemade. If it's for dinner it won't be particularly exciting, but I'd do a homemade chilli or lasagne, something easy to prep ahead and feed lots of people..
Among my friends no one cooks, to the extent that it feels pretentious to do so. They are all generous hosts, but everything will be from a packet or they'll suggest takeaway pizza or similar.
I worry that my cooking seems like showing off and also (sometimes) wonder why I bother!
