Whats the worst birthday youve ever seen?
It can be yours, or someone's else.
Thankfully for me, all my birthdays - unlike the Christmases - have been quite happy. The worst birthday I had the displeasure to see - and to organize - was one for my mother many years ago.
No smiles, no nothing. She woke up at 8PM, the only comment she made about the cake I had baked for her was that it looked like a ''t*rd'', and she wasn't happy about the gift too - a perfume bottle. Was kind of depressing.
What about you?
