I slept with you on Tuesday...

So I answered an interesting phone call last night. My phone rang and I didn't recognize the number but decided to answer it anyway:

Caller: Hi, Sarah?
Me: Yes...
Caller: This is Dennis. I slept with you on Tuesday.

Immediately I'm trying to figure out how who would start a conversation like this. I'm pretty sure I'd remember if something like that happened. Surely he has the wrong phone number. Right? Except he knew my name...crap. Who do I know named Dennis? If he's starting a conversation like this, I don't think it will end well. Maybe he's calling to say he has an STD. Well, I know he didn't sleep with me so I know I'm fine. Oh, I should stop him before he tells me something I don't want to know! What's a polite way to respond?

Me: I'm sorry, what?
Caller: This is Dennis. I subbed with your on Tuesday.

OH! Subbed! That makes things much less awkward. Wait, subbed what? Oh, I get another person's e-mail from time to time and she's a teacher. Maybe he thinks he's talking to her. But she lives in Chicago. How would he get my number. Well, maybe I can see what he wants and I'll figure out how he thinks he knows me.

Caller: In volleyball...

Crap, I waited too long. OH! Volleyball! He's the guy who played with our team because one of our guys was going to be gone!

Me: Oh, Dennis! Hi! What's up?
Caller: Well, we were looking for a sub for Sunday night and I was wondering if you were busy.

So, the conversation wasn't actually as exciting as I originally thought it would be. And Dennis wasn't trying to deliver bad news to a one night stand. However, the few seconds spent trying to figure out how to politely tell him he had the wrong person definitely provided some laughter later. Honestly, if a conversation actually starts that way, it can only go downhill. It did make for a good laugh given that I just have a hearing problem.
