He wants to change days for this weekend....
You know, my 1st wife use to pull that crap when we split. She wanted to switch visitation around based on what ever social agenda provided the best value for her. I said no from the git go, "I have them Friday, you have them Saturday, that's what we agreed to. I don't make plans that can't include the kids on days or nights that I have them." End of conversation.
Man that use to **** her off because it implied that she wasn't a good mother. She had the kids low on her priority list for a while there.
