Since right around January 1st, most nights at 8:30, we hear a "thump, thump" coming from the room right above ours. And it's loud. I'm sitting in the living room and I can still hear it. Apparently ( I haven't asked them or anything but I figure) they have decided to shed the pounds gained from the holidays by walking on their treadmill with very heavy steps.
Although it's better than the last time we heard a "thump, thump" from upstairs neighbors. (some of you may remember what it is I'm talking about; if you don't, trust me, you don't want to know.)
At least this is honest exercise.
