I'm so cross that I have hung up on my mother, first time in 45 years.
First off, I am not bothered about today for me as I don't really do cards, gifts, etc - I know my ds loves me and would much rather a hug 
However my mother doesn't believe in this, and thinks that only visits and presents show how much she is loved. Therefore we have visited the last two weekends (40 mins each way) for a spontaneous visit and a birthday visit. We normally visit every 2-3 weekends - ds has orchestra and swim training on saturday mornings and sunday afternoons, so we fit it in as best we can. We both work Mon-Fri and look forward to spending some time with each other at the weekends, shopping and general stuff around the house.
My parents knew that we wouldn't be over this weekend, and I said that I would ring on Sunday when we spoke on Friday. Unbeknownst to her I had ordered some flowers and a card to be delivered today.....so I hadn't rung so far to give them a chance to come - probably my biggest mistake!
Just had a sobbing phone call saying that it would have been nice if we had come, she's been waiting and listening for the phone. Oh, the flowers are nice but it's not what she wanted. Now I feel so crap about something that I thought was nice, but maybe I shouldn't have bothered
