It never fucking fails. I paged the maintenance people at ten past the hour to ask them to come retrieve the electric razor blade I dropped into the sink hole. I putzed around for a bit, then decided that I could afford to run out to the mailbox quickly to drop off a letter. It took less than a minute, but as I opened the door returning to my apartment, I heard the phone ringing. I raced to the phone, picked it up, but there was no one on the other side. Grrr. Now I don't know if it was the maintenance people or someone else who called. No message.
