I haven’t actually forgotten, I remembered and sent a message but with other personal things going on I didn’t drop a present/card to my friends daughter last week, she is now upset with me and has told a shared friend of ours how upset she is that I “forgot” and it means our friendship isn’t what she thought it was.
we have been friends a long time and I always acknowledge her children’s birthdays and any other event in her/her children’s lives, she doesn’t do the same to mine, which I have never made any issue of as that is her choice.
am I unreasonable to think this is unfair?
