My unmarried, childless (too much time on her hands) SIL has texted my DS1(19), who is away in uni, to remind him it is his father's birthday tomorrow. DS and I bought his present weeks ago and he doesn't need reminding and if he did I would have done so before today. DS is offened she would think he could forget and doesn't think it is her place to remind him. She has requested him as a friend on facebook and he has declined but she can't take a hint and butt out. He is really enjoying being independent and doesn't want or need her treating him like this, I don't and I am his mother, I suppose that is why we are close and he hasn't got time for her.
I think she is lonely and have always been welcoming to her but as time has gone on and she has tried to interfer too often I have lost patience and now try avoid her, which is what my DH has been doing for years. This latest trick has made me spit feathers, am I over reacting and AIBU?
