I mean, will your kids wonder why they're not going to grandma's house, or will it be no big thing??
I mean, if your kids don't notice or won't care, then **** it, don't go.
If there will be awkwardness and tension for you kids to pick up on...the **** it, don't go.
I wouldn't take my daughter to some bullcassel like that.
Sit on it, Potsie.
