Eight or nine.
A girl came into school the day after her mum told her Santa wasn't real and ruined it for our whole class. Like a week or two weeks before Christmas. All of our parents were furious.
lol @ all of these people acting tough and saying "I never believed in him at all"
But I was probably 10ish
I was seven when other kids started to bully me for still believing in Santa. How sad. My parents finally told me that Santa didn't exist when I was nine and I had a meltdown.
