When my son was three, we lived in a small cottage on the Oregon coast. One day while we where at the post office, we saw a big cardboard cut out of Santa Claus standing next to a mailbox that had written on it, “Santa Claus, North Pole”. We decided to write a letter to Santa. He told me what to say and I wrote it. Then we walked to the post office and put it in the red mailbox that the cardboard Santa was standing next to.
In the letter he asked for a flashlight and a rabbit cup for Christmas. We were gone at Christmas. When we came back there was a package on the door step. Inside was a flashlight, a rabbit cup and a box of chocolates. The box of chocolates had a note on it that said “For my folks.”
The only thing I can figure out, is the mailbox wasn’t for just any kid to pretend to mail letters to Santa, but for serious requests only.
