My big pet peeves are the widespread belief in this society that:
a) it's your right to tell other people how to be parents
and
b) mothers must achieve a perceived standard of "perfection" which is absurd.
You must literally be nuts to suggest that a parent (mother, specfically, natch) can't have a drink if children are under their care because maybe, just maybe, they'd have to drive them to a hospital if a kid got hurt.
If I had a sick kid I'd hail a cab to the hospital, now that the one a block from me has closed and I'd no longer be able to just quickly walk to one.
