Ok, so I was supposed to take my son for festivus (friday dec. 23) at about 8pm. ok fine, so my family will have a little christmas thing on the 23rd, no big deal with me. my mom invited some family over, i must have told her my son was coming earlier. I got a job today, and have to work til 10pm on the 23rd. i told my mom my son would not be over till 8 or 830. she was pretty bummed about that and wanted me to try and get him more like 6 or 7. i called my ex, and told her i had to work til 10 and that my mom was hoping my son could come over around 6 or 7 (to hang out with the fam). she (my ex) told me that wasnt happening. so i gave in, because i didnt want to get into a fight. so now my mom is disappointed, and im bummed because of it, i get to see my son for about 8 hours (in the morning) on christmas eve, but at least my ex is happy. thoughts? ideas?
