Is AUTHOR wrong in the post ? POST : I have just been confronted by my apartment building neighbour's friend that live below me for making too much noise the day he is moving out.

&amp;#x200B;

A bit of context, I live in a apartment with a friend and we are musics and films enthusiast, so we like to listen to music and I myself play a little of acoustic guitar. We have a Ultimate Ears Megaboom speaker that can output approximately 90dBA. So when we arrive, we start at medium sound volume and we increase it from time to time since we didn't have any complaint and sometimes we played it at full volume during party on the weekend so we can understand that it can be loud but we were careful to not let it sit on the ground to avoid vibration.

&amp;#x200B;

But 6 months after we move in, our neighbour below us is moving out and a friend of him come knocking at our door saying that we were bothering his friend during this time and was pretty angry. We said that we were sorry but he could have come to us to explain the situation before and we would have been polite and decrease the volume so we don't bother anyone. What's bug me is that he never said anything and a friend of him come to us to complain the day he leave.

Am I an asshole?
