I'm sorry to hear about your Grandpa. That's terrible news

I'm appalled that those parents behaved that way when you told them. Of course you're going to be by your mother's side! That shouldn't even be a question in their minds. Go and be with her and let the families sort out their situations. Goodness knows they'd not think twice about taking off for a lot less than a death in the family.

Ass hats was perfect terminology.
