My mom led me to believe that when I was turning 10 that I could really be 16 if I wanted to skip 6 birthdays I was really angry with her when I found out it wasn't true.
A childhood belief about birthdays

others believed things like this
- I used to think that if you ate cat food you would die. I found out it wasn't true
— Bob#4 - I thought the song Skip To My Lou was about skipping to the toilet.Anon
