thank heavens for that! I for one hate surprise parties. My idea of the perfect b-day is to sleep long, have a chocolate croissant for breakfast, sit in the sun doing a jigsaw puzzle, have pizza for supper and go to bed early with a cup of tisane, one of my favourite books and a handfull of chocolates. And in between all this maybe a chat with my friends online
Yeah, you want the person to enjoy their birthday, not give them a heart attack.
Anyway, a birthday is whatever you want it to be. Doesn't have to be extravagant, but just make sure you enjoy it.
