you're who?

As an online gamer, I often encounter situations that display just how lonely and desperate for attention some people are. The other day in Warcraft, I was getting ready to log off for a break and someone used the /wave emote at me. I /wave'd back and kept on doing whatever I was doing. He kept using friendly emotes and I ended up /dance-ing with the guy. Then I logged off and forgot all about it. Why? It's an RPG and I emote with people every twenty seconds. Anyway, later that evening I logged on and someone immediately sent me a /whisper saying "hey, how's it going?". Considering the fact that each of my friends has as many alts as I do, I figured it was someone I knew or someone in my guild. After a few minutes of polite conversation, I was still clueless and asked who it was I was talking to. The response I got was, "You don't remember?" I replied, "No, I haven't a clue who you are." At this point, I figured it was someone in my guild and my crap-ass memory had failed to recognize the name of the character. Not quite so... the reply I got was, "You danced with me this morning outside the inn!" At that point, I was at a complete loss for words. After a few moments and a few more awkward things messaged to me about the whole dancing event (that I had only a vague recollection of) I politely said I had no clue what he was talking about. He had obviously added me to his Friends list, otherwise he would not have known I had logged on. The last message I received once I told him I was clueless was, "Oh." And that was it. As awkward as it was, I felt bad for whoever was on the other end of that character. Some people really just need a friend.
