Does your complex have rules about noise? Usually there are rules limiting noise to certain hours. You should be within your rights to play music at moderate volume at 3pm. It's up to you. Does the neighbor own guns?
Apartment Drama
Hi- I recently moved from my house to a 2nd floor apt with 1 apt on each side and 1 below. 3pm today I turned my stereo on for the 1st time. Low volume IMO. Hard to describe but no problem having a conversation without even raising my voice. within 10 minutes my neighbor knocked on my door acting irratated demanding I turn the volume down. WTF? Now what. Do I have any rights or do I have to obey this jerk?
