I have a very vague memory of sending a letter to Santa. I can see myself in my mind reaching up to put the envelop addressed to Santa into the mail box. It was really high up and I had stretch to reach it. I can even see me in my winter coat with the matching hat and snow pants. My Mom was big on snow pants.
When I was 10, our last Christmas in New York I learned who Santa really was, I recognized the hand writing. Of course I became part of the secret Santa society because I had younger brothers I could not real the identity of the special person.
Do I still believe in Santa? Well how do you think all the gift tags in this home are signed by Santa.
Did I mail letters to Santa with my kids? If I did it, it was only with the youngest, he was 7 when I married my hubby and his 3 kids. The other two were 11 & 10. Some how again the memory is vague.
My suggestion would be to take a photo of the event so you aren't left with vague memories, and scan a copy of the letter and envelope. Save the memories!
Have a Merry Christmas Season!
