For the last 2 days our upstairs neighbors have decided that 1 or 2 in the morning is a GREAT time to scream, stomp/run across the floor, and play music with a lot of bass that shakes our apartment. Lovely. Earplugs are the only thing that helps, luckily I can just barely hear the baby when she cries with them in, but it does kill the music.
I feel your pain on dealing with lousy neighbors. Be nice and ask them to be respectful of the time. Or, be not so nice (like I’ve been) and say “Dudes. Really? You wake me or my newborn up one more fricken time and you will NOT be happy with me. I promise.”
Or, if all else fails–turn them into the apartment office. Or, call the cops. It’s crap to have to deal with that.
