Normally I don't have any problems, and really, I wouldn't have minded that time except it was annoying for those fifteen minutes that I could hear them because I was so sick. They're pretty great to have for neighbors, and I've been over for drinks a few times. I never hear anything from my neighbors to the side, except when I'm going out and at my door I can hear them playing video games. So, basically the exact same situation for them.
I'm pretty lucky, actually. The only really shitty neighbor I've had was the one that I bitched about on here a couple of years ago--the one that had the cops visit three times before she finally got evicted and I no longer had to hear the muffled sounds of her shitty fucking music.
