I'm a glancer; I read the headlines on other people's newspapers, I try to find out - surreptitiously - what the stacks of photocopied papers, with or without graphs, are about, which books my fellow travellers are reading etc.
The only thing I do not do is read other people's writing.
However I'm not surprised that others are curious when they see me scribbling in my little notebook. Yes, it bothers me, but I try to cover up the more "sensitive" passages with my hands.
Sometimes I forget, though. Like yesterday, when a gentleman glanced at the notebook I first wrote this little story in while we were both getting off a train and the first words he must have read were "whilst trying to enter a public convenience".
