At 3:28 p.m., someone pulled into the parking lot here at London Square Apartments near my building. Said driver had his/her stereo blaring loud enough to shake the windows.
Edit: At 3:31 p.m., the Upstairs Stomper started stomping around upstairs. Interesting how these two noisy events seem tied together. But given that yesterday's loud stereo action was approaching harassment levels, and given the history of "bad blood" the Upstairs Stomper and I have, it wouldn't surprise me if the offending outside stereo belongs in the Upstairs Stomper's vehicle.
