A knock on the door and there stood a chubby young lad with my computer. He came in and set it up and was telling me in computer jargon what he'd done...and how it was running now. I offered him a drink and as he drank it we were talking. His name was Richard, Rich, he was 24 and in his own words a bit of a 'geek'.As we sat on the sofa talking he said "I live my life for the internet, looking at your history so do you", I said "I don't know what you mean", he smiled at me and replied "I've seen.

The next thing, Deb asks me to stop, saying she doesn't like it me doing that. I'm busted. She gets up and leaves the room. I think to myself that I'm in deep shit now.
