Clean it up...

I like dogs. You know where you are with them. If a dog likes you, you know that liking is genuine. People are altogether more tricky. We have a lot of dogs living in our neighbourhood but you don't see them often. They're a well behaved lot not given to wandering about on their own making a nuisance of themselves. You do see them out and about at certain times of day exercising their humans. That done they all go home.

I'm not sure if some of the humans are doing what they should do when they are out with their canine companions. These signs have recently appeared stencilled onto the pathways as a gentle reminder.
