Our neighbor, it would seem, has embarked upon an exercise routine. Every night, for at least an hour, and sometimes much longer, there's an odd rhythmic thumping coming from upstairs. I'm fairly certain it's a treadmill from the sound, but I'm not positive. If it were only a few times a week for 20 or 30 minutes at a time, I could probably live with it, but this is often close to a couple of hours a night, every night. I'm debating how best to handle this...I'd like to approach them, and ask them about it, maybe see if they could move it to the opposite side of the apartment so we wouldn't hear it as much. Any suggestions on how to word things?
