Having A Sharpie In Public
Owning a Sharpie pen may seem like something that is totally innocuous, but taking one out in public can definitely lead to trouble as police can consider it as a tool for graffiti. Not only that, some students have even been arrested when using such pens in school if they have bled through the paper onto the desk and left permanent marks.
Singing Happy Birthday In Public
While there is nothing wrong with singing songs in private as copyright laws don’t have legal weight in that situation. However, singing them in what can be considered a public performance, determined by the number of people involved and the volume of the singing, can be considered illegal as you aren’t paying any royalties to the copyright holders. Thankfully, this one does not hold anymore as the copyright has been removed.
