DH away for work for a week at the moment, no offers of help from family or friends etc.
Last month I went away from 2pm Friday until 5pm Saturday, MIL took kids over night, friends came round with tea for kids when DH got them back etc etc.
Seems like everyone assumes the kids are my job - but poor DH if he gets left alone with them then that's just unfair 
(Just to add, DH is a great dad and very capable. It isn't him who i think is being sexist. And it's not that no one offers to help that irks me, just that family fell over themselves to help DH for the ONE NIGHT that he did on his own.)
