i don't think facebook knows me at all

Or does it know me too well? No.

worst of all

However, not only have I been acting strange I have also been thinking strange. For instance, our neighbours up the road have a van parked outside with 'Pergolas and Decking' written on the back and a phone number. I honestly thought to myself, Hmm, Pergolas and Decking, I wonder what business they're in?
