That didn't take long.
The Friday before last I noticed that a maintenance worker had removed the lock box from the door to the recently vacated apartment next to mine. Would somebody be moving in so soon? As it turns out, yes.
Since I've not been home much these past couple days, I haven't seen who lives there now or if they're even fully moved in. There are two names on their mailbox, so at least two people will be occupying the adjoining apartment. Fingers crossed that they're already settled in because there's been no noise at all so far. I welcome this continuing.
