Argh I'm so annoyed at myself, upstairs are three young guys who like to play instruments, I have no problem with this but they were banging on the floor off and on for last three hours. I knocked and told them the music was fine but could they stop the banging as it traveled thorough the entire apartment so could be heard in every room, they were super apologetic and I reassured them several times the music wasn't an issue, now they have stopped playing altogether and I feel ridiculously guilty even though the banging was stressing me out! Am I totally pathetic?
