Nice things to do for people on my birthday?

Happy Birthday for tomorrow, and I think that's very kind of you to want to brighten other's days up. You could try smiling at everyone you p in the street, whether or not you know them. If there's someone you haven't ever really seen eye to eye with, you could try talking to them. If there's someone at school who is usually left out of the group and tends to be on their own a lot of the time, go up to them on your own and offer to be their partner, or ask if they want to join your group. Buy a box of chocolates for your friends. Do the cleaning for your Mum and Dad. Donate some money to a charity. I'm out of ideas now, but I hope these ones helped :)
