When we were newly married and living in a garden apartment complex on the first floor, we had an upstairs neighbor who was a medical student. He was a cigarette smoker and every morning we could hear him hacking his guts out coughing for at least a good three to five minutes. He was also loud in other ways, including playing his stereo really loudly.

We tried talking to him to no avail - he became pretty obnoxious. I would take to putting one of my own stereo speakers up against the ceiling playing classical music at full volume, but he just turned his massive system up louder that mine.

We finally had it after months of lodging complaints with management about him disturbing us. We put Crazy Glue in his apartment door lock.

He must have tried for half an hour to get his key to go into the lock with no success. He finally had to call the management office to get somebody to get the door open and change out the lock.

Shortly after that he moved out.
