I was 10 years old when I found out. For as long as I can remember, I received a letter from Santa every year right before Christmas. So one day after school, I thought that I’d be helpful and get the mail for my mom. I saw a letter that had in fancy print the word ‘Santa,’ so without reading the rest of the envelope, I immediately assumed it was for me and opened it. Turns out it was the paper my mom filled out so they could personalize my letter. I was so bummed out after that.
