Going for lunch with friends, I take a handbag big enough to fit a couple of books and toys in for dd. Rushing to the train (with dd in baby carrier) I think my bag feels a bit heavy, that's annoying. Get on the train and DH has stashed his fucking 1100 page book in there!
He doesn't see the problem as I was "taking a bag anyway." Yes, but I wasn't expecting to carry a fucking brick around. On the way home now and he's managed to read it for all of 10 minutes. Worth it then 
AIBU for not wanting to be his pack horse? Anyone have a man child who thinks their handbag is there for you to carry his shit around?!
Not the first time his has happened, you may be able to tell...
