You should be more careful when reaching for things on a shelf. You can buy a step ladder you reach things in the future and prevent injury.
Every person makes mistakes, You should move on.
I understand everyone makes mistakes, but this was a painful one and I'm trying to help you prevent them in the future. Just being a little bit more careful could help you not get hurt for a while, and that would be nice, wouldn't it?
