Blue Monday

We live in a first floor flat and look out onto a fairly busy road, and can see into most cars. I was standing on our terrace (so called because there are no words to describe it as otherwise) and chatting to one of our neighbours when I looked down only to see a man driving his car with a porn magazine on his knee and clearly looking at it whilst driving. Now, aside from the danger, what sort of pleasure was he getting from looking at naked ladies whilst driving?!
