My DH is making sandwiches for us (me, him and DD) for a train journey tomorrow. He cut up DDs sandwich and went to wrap up the 'adult' sandwiches without cutting them at all. I asked for my sandwich to be cut in half. He said I was being ridiculous and that "no adult needs their sandwich cut up, that is how children eat sandwiches". I insisted that he cut up my sandwich in half, then a jokey argument ensued about whether adults eat their sandwiches whole or not. I am firmly in the camp that everyone cuts up their sandwiches and he is being weird. We've decided to put it to the hive mind of MN.
YABU - adults eat sandwiches whole, not cut up
YANBU - he is a barbarian, of course we cut them up
