I was just about to leave the house on Saturday to go to Boston to visit some family when the buzzer rang. I asked who it was, and there was a muffled response. I thought it was a delivery person and I'm expecting a delivery so I pushed the buzzer. I stood out in the hall and waited. A minute later an elderly black man who was blind in one eye appeared at the top of the stairs. A young girl, I would guess 12 years old, stood behind him. The man said something about "The Watchtower", and I knew who they were. I asked them to leave saying I had accidentally buzzed them in, but I must ask them to leave the building. I didn't want to be "that guy" who let the Jehovah's witnesses into the building, like Elaine. The young girl turned to leave, but the old man persisted. I had to walk them out to the front door, apologizing the whole time. Then after we exited the front door, they stood at the stoop, looking as if they were going to just keep buzzing other apartments, so I stared at them, incredulously, and asked them to get off the stoop and I apologized to them.
