Every year it is a reminder of how disfunctional my Mum is (depressed alcoholic for 30 years, violent, manipulative etc) and how we do not have any semblance of a relationship left. I dutifully send a card, gave up on pressies years ago when even I realised what a sham it was to pretend that she was a great Mum. Mostly I don't think about her as she is almost a recluse now and all contact is through my long suffering (weak) Dad, but sometimes I feel sad and mourn for a relationship which I have not had since I was younger than ten. Sorry, feeling a bit down about it all.
I know these things are just commercial crass, it's like Christmas, everyone assumes the mother/child relationship is sacrosanct.
