Last year I had a big birthday. My oldest friend of 30+ years pretty much ignored it. No card, no present, made no effort to come & see me even though I made every effort for her big birthday the year before. So I have taken a massive step back (ie made no effort for last year's or this year's birthday or Christmas last year, haven't seen her in over a year though we message occasionally). I wasn't able to tell her the reason she pissed me off as she was ill just after my birthday last year & I didn't feel it was appropriate. Anyway just had a text from her to say "hope you're OK. Just to say I'm not doing Christmas for friends this year". Obviously I wouldn't expect anything from her as I don't plan to see her. I feel like replying "well you started the tradition on my birthday last year". Can anyone come up with something more grown up? Or jusy not respond at all?
