Snotty Step "Kid"

Sometimes, it's hard to remember the sweet little girl a stepchild was 10-15 years ago when they've grown up to be snotty adults.

Getting real sick of her snottiness towards me on Facebook.  I'm thinking blocking might be a good idea. It seems to me that all these years caring for and about her should mean something and that "blocking" would never be an issue between us but...

I don't deserve her snottiness.
I don't have to put up with her snottiness.
My kids shouldn't have to see her snottiness.
My friends and other family shouldn't have to see her snottiness.

You'd think since she expects a Christmas present (she's already told us what she wants), she'd turn off the "snotty" until December 26th.
