Stalking has never been a forte of mine.
When we were younger, my mate and I used to walk behind folk in the town, impersonating the actions and the motions for as long as we could before we were noticed, but that isn't stalking. That's child's play.
With the internet today, it's very easy to keep tabs on folk. There are so many social networking sites, and so many ways of accessing what everyone is doing and saying. You don't actually have to be in touch with someone to know what is going on.
A Bit Devilishly Scary isn't it? Think on.
