I have a week off work and it is also my birthday on Wednesday. My colleague normally brings her kids in to see me during school holidays. I haven't let her know I won't be there tomorrow as I don't feel I have to let her know my constant whereabouts when she doesn't give me the time of day anymore. She also is kind of spadoric when she brings the kids to see me anyway. I guess I just feel guilty as I think the kids may be disappointed tomorrow when they see my colleague instead of me. I am really close with them but not their mum anymore (She used to be a friend). Am I doing the right thing just letting her show up and not finding me there? As I say I am not friends with her anymore and I figure that if she is that bothered, she would ask me herself.
