Am I single

I do not believe how much confusion one statement can create. A long time ago, I put a statement on my ICQ account that I am single. Quite innocent. But it seems that people think the I am a single when I make this statement. Now, I have nothing against the singles of the world. In fact i am impressed. But I did mean that I do not have a girl friend. In the end I have deliberately not changed the statement. But I have not made it anywhere else. Out of curiosity I just had a look for my ICQ account and find that it seems to have expired.

So two statements, very different meanings:

1. I am single.
2. I am a single.
