My ex just asked me if he can come at 10am on Tuesday to see my son... Like really? My mom doesn't see the issue with it but me and my son typically nap in the mornings. I work out and this just means I have to get up at like 7 to do what I have to and at least shower before he comes. And I can almost guarantee my son will be tired when he gets here. I don't get why the guy can't come on the weekends at like 1. But he comes during the weeks and takes time off from work it makes no sense to me.
