crazyH, my Mum and Dad always made an effort for my birthday and those of my siblings, even though money was very tight at times! I had family birthday teas, cards and small presents from parents and my brothers (obviously courtesy of Mum and Dad!) and Mum was very good at baking so a home-made birthday cake was a highlight! I don't remember ever having a party with friends but then none of my friends at school had them either so I didn't feel hard done by! Just the way it was, and we always felt loved and secure so that was more important, I think.
I really didn't have a particularly close relationship with my GM, but as I said I hadn't ever known any different so it didn't make me feel sad at the time or even now, to be honest. What you don't have, you don't miss!
