The fact is that the girls were teaching Karthik how to use the computer for more than email and chat. It was a good lesson for him as he had to learn mouse control and hand - eye co ordination. Those that have seen Karthik tripping all over himself will understand.
Kudos Karthik for attempting something new at your age (I now duck for cover).
BTW Brandon, could you put Karthiks' name into spell check. It's bad enough that I type it but to have to see it again in spell check....
