Saturday is Sticker Day
On Saturdays in HK, wherever we go we bump into schoolkids selling stickers for charity. They all have a cool little money bag that you drop your coin into (doesn't matter how much you put in) and then they put a sticker for the charity on your shirt so you don't get asked by other kids from the same charity. It seems nice - not as intrusive as a tin-rattler at an intersection back home. Maybe I could start collecting them.
