Still....can't help but wonder if they know something we don't. I would be checking the ground really carefully
lol
Reminds me, one day it was a really sunny warm day and I was in town shopping and in a really silly mood. I was walking along in front of a shop and being late in the day there was a couple of shadows from parking meters and a crossing sign, close together but extending across the footpath. Two middle aged ladies were walking one way, my (ex) wife and I were walking the other and we converged on the shadows. On impulse i started lifting my feet in mock panic and pointing yelling at the shadows, don't step on them don't step om them.
Well I don't know if you have ever seen two ladies trying to walk but do it by keeping both feet off the footpath at the same time, god it was funny. I just about cried laughing. The ladies thought it funny too when they realized it was a joke.
