AIBU To expect my step kids to...

[Pringlesaremyspiritanimal]

... say hello when they arrive and goodbye when they leave? They’re 9, 11 and 13, have been with their dad for five years.

A bit more Info needed OP- What’s your relationship like with them in general? They just walk in and don’t acknowledge you?

As a moody teen/tween I used to ignore everyone 😂 possibly we need more context.
I’m sure they’ll grow out of it.

No yanbu to expect the most basic of manners in your house.
They don’t have to be friends with you or even chat to you but I don’t think you are asking too much.
