Have you ever found a note in your notebook or a letter you don’t remember writing?

When I was in 5th grade my dad saw a note in the middle pages of my notebook cursing my parents (saying theyre shit and they should die) and got mad at me for it though I wasn’t the one who wrote it. Up till now I’m still clueless as to who wrote that note on my notebook, whoever they are I just want to ask them why of all notebooks they chose to write on mine.

It wasn’t even a small note. They wrote it in all caps with a marker occupying two whole pages so it was easy to sight.
