So bit of back story for this one. We live in London, oldest DC is very set, and has always been very set, on going to a university on other side of London. DH has been vocally against this, though he accepts it's DC's choice, as he massively regrets staying in London for his degree. Personally I think that's his problem, and also he stayed very close to home, unlike DC who will be living a good hour's commute away in a very different part.
DH has continued to carp about it and told DC today he would be 'gutted' if they go to the London uni as he so regrets being in London and DC indicated they'd heard him. He then said 'Is that "Sure, I hear you and I'll consider it' or "Sure I hear you and I'm ignoring you"?' which I thought was really unfair - he does do this sometimes, like makes things really personal about him and poses questions in a way that forces you to frame it as if you were deliberately being unkind or unfair to him. You know, he could have said 'I hear you, but I have made up my mind', which isn't putting such a negative, personal angle on it. And his feelings about it are not DC's responsibility.
FWIW, I'd rather they went out of London - I don't think they'll regret staying, but I think uni is a great excuse to try somewhere else at low personal cost, and it gives you a different perspective. Also I worry slightly about the financial status of this London uni and whether they'll get a good learning experience as I know people who've worked there and I fear they may end up with a bit of a revolving door of tutors that might not be great. But DH (and MIL) carping on about it have pretty much made it impossible for me to make any argument about it. I think they do have some sound reasons for choosing the London one as well in terms of career development
