Alternate Vision

Friday evening rolls around and in my hurry to drop of my stuff and make it to the GSA happy hour I lock myself out of my apartment. Splendid, indeed. And yea don't ask why I hadn't made a spare yet. After much contemplation I decide that calling Paula, my 80 year old landlady, would be inevitable. But alas the spare keys would not be delivered for another hour and a half. So I change plans and decide to hit the happy hour anyway, wash away the guilt and return when the keys were ready. I called Gaurav who was on his way to pick me up and decide to soak up the sunshine by sitting by the doorway outside my apartment. Enter Ben, the compassionate, friendly neighbor. Since it was our first meeting, pleasantries were exchanged ofcourse. Then,
Ben: "why may I ask are you sitting out here?"
Me: "Locked out man, and its only my 2nd week here"
Ben: "Oh, I think I can help you out."
At this point I was a bit confused, though hopeful nonetheless.
Ben: "Follow me"
We proceed on upstairs towards my apartment
Ben:"I tried this once before and it worked. I pray to god it doesn't work again."
He walks up to my apartment, sticks his key in and voila, like magic it opened. Now, who was this Ben? Was he really my neighbor? How did he open my apartment? Could his key open all the eight apartments? Could my key open all the eight apartments? I didn't know whether to rejoice or panic. Before I could mentally process what had just happened Ben excuses himself and leaves. If I decide to tell Paula, am not sure what she is going to think. If I decide not to tell her I am just living of the assumption that all my neighbors are a)trustworthy, though I know none of them and/or b) not all of them know of this "secret." I could sue for this sort of thing, but I won't. Weird.
