the letter from jail

a old friend from high school sent me a letter from jail the other day . "“I know I've caused you a lot of grief,” the letter says, “but there’s something I need that only you can get for me. Don’t tell anyone about this.” it was our freshman year and the teachers gave the hole school a key. And if the key fits to the schools basement door theirs a hundred thousand dollars in there .and im the only person that didn't put there key in the door . and now hes wanting me to bail him out with the money
