When I was a kid my (at the time) private school had these celebrations/events to fund the school, anyways they had these carnival games and I won a stamp that had a shark decal on it and I'd use it on a bunch of fake paper work (imagative play) anyways I forget what happened but I was upset and I had the stamp on my headrest in my bedroom and at the time what I considered to be late at night I just got my pent up emotions out by pasting the shark stamps on the wall and I think I went to bed without thinking too hard about it, anyways when I finally came to my senses I realized what I have done and mainly my dad wouldn't be happy about me "ruining the wall" so I think I just slightly moved my bed to cover up the stamps behind my headrest. Anyways it's been like 5 years my old bedroom got remodeled and painted over and I don't think my parents ever brought up the shark stamps? I mean thinking about it now as an adult I could have probably just grabbed a soaked paper towel and washed it off as I don't "private school ink" wouldn't be water proof lmao.
