We enjoyed carolling and having carollers stop by the first three weeks in Decemeber. That is when I was growing up and my neighbours were neighbourly. That isn't always the case these days.
We used to get together with a group of my parents friends and their children and we would go carolling to raise money for the Santa Fund. I used to get excited when carollers would come to our door. I'd rummage through my coat pocket in the closet or dash upstairs and check my piggy bank. I'm sure I only gave them silver coins, but I felt like I was thanking them for brightening my day. (Anybody who attempts to sing Silent Night and hits that high "Peace" note deserves some reward.) Sometimes my mom would come to the door too and they would get more out of her.
When I was in High School I was in a Puppet Troop called, Smile Inc. and we put on Christmas puppet shows with Muppet Style Puppets we made out of polyfoam. I was the voice of Santa and one of the elves. We took the puppets and one person dressed up as an Elf (costume from a school play) and we went carolling. There were six of us in that group. We made hundreds of dollars and covered three or four miles of houses.
I haven't had a knock on the door from carollers in fifteen years, nor have I knocked on anyone else's door. (Likely a good thing, since I don't sing all that well.)
