I've had this a few times and it has always wound me up. I'm a phd student, so work in academic circles. At two conferences recently, I have been asked this by strangers! And it is always by people whose parents have "high-up" jobs.
AIBU to think that you shouldn't judge one on their dad's job?
I get that if you were building a friendship, then this would naturally come up; but asking a stranger? No!
By the way, I am in no way embarrassed about my dad and what he does for a living! He was a retail store manager, a decent profession by all means!
BTW, fuck the Daily Mail! (To stop them lifting this thread!)
