About a year ago, I was walking to work when a rat came out of a shop front and trotted along beside me about a foot away from my feet. he seemed startled when he finally spotted me and dived down a path into a kind of field. I was a tiny bit scared in case he decided to attack my feet (I was bitten by a rat years and years ago and had to have a series of nasty injections) but at the same time I was intrigued. They are intelligent animals.
