@4rky yes lots of snakes do, and I didn't tell the story here about what I suspect is this very same snake, and a frog, right at my back door only the day before! sadly despite some incredible screaming, the frog did not survive even though I unintentionally scared the snake off ... well remembered that I've talked about this!
@happysnaps yes indeed, and I had seen this one the day before and so was a little bit 'snake wary' as they do make me jump, then go 'nawwwww .... how lovely!'
