Neighbor's moved out.. Either something in their security system or a smoke alarm was going off all of the fucking time *chirp*. Had to call the realtor to get it fixed, it was so fucking annoying. That and I think they realized that a possible buyer would not be happy to tour a house that had chirping alarms going off. Kind of makes you think the place was not taken care of.. Also, no. The neighbors were not basketball American's. The annoying chirp started about a month after they moved out.
