I read the mail of my parents after they went on their date night.
What was your reason for thinking it was ok to go through their things?
Whatcha gonna do about it, I don't care what you say.
What if there was something personal in their mail. You should not read their mail since it is not even addressed to you!
I don't care if they die tomorrow.
Well that is a pretty dark thing to say. Your parents love you and being ok with them dying is sad. Ultimately, you should also not go through other people's mail as it is an invasion of privacy.
