When you start webcamming with someone just for the sole reason of doing a virtual High Five, you should be aware that you've been on the computer for far too long.
If I could be bothered finding out what your msn address was, I'd add you and high five you via webcam...
You haven't been on the computer too long till you're on msn, asking a person you've been talking to for half an hour if they are free to talk...
