Going the wrong way on the escalator
I spent a lot of time in hospitals as a kid due to my grandma and one hospital has escalators so I decided to try to be cool like Henry and the gang one day and decided to go the wrong way on it but instead of going down the escalator that went up I tried going up the escalator that went down.
I must have fell 5-6 times and scrapped and bruised my knees and elbows all up pretty bad and this is what happens when children try to imitate what they see in movies.
