When I was around 7 I was having doubts and started looking for presents. My parents had a camp trailer and for some reason I saw there were tracks in the snow leading to the trailer so I went over to the door and it was locked (which my parents NEVER did)
This was a older trailer and you could access the storage from the outside and crawl in and pop open the cabinet door under the couch. We did it several times I knew everything I was gonna get down to the candy LOL We were so bad
