SIL is trash person

I guess I just want to get this off my chest.

My SIL just dumps her two toddlers on whoever so she can go party and do drugs with her trashy friends. Then turns around and pretends she gives a shit about them to whoever asks about them.

Those poor kids (their Dad is dead, also was trashy)

I wish my husband had a better sibling. His only sister turned out to be a piece of shit

EDIT:

Can't call CPS, she doesn't do enough bad stuff to warrant them doing anything. Shes just a shitty mom, but they are clothed and fed and have a roof over their heads. Not much else but that doesnt matter.

Also we can't take her kids in. We have our own and her kids are kind of wild and out of control. We gotta focus on our kids.
