...good question. No point being hard if you're stupid with it. Real hard men control their temper and get things done quietly...it's not hard to hit people, any prat can do that. (Sorry..this is mikeo..didn't notice I was signed in as Joshua )
There's a footpath at the end of our cul-de-sac to a park so the road (and park) is constantly littered with dog-shit (there is a bin for it which people ignore). I'd happily push the owners face into the shit if I spotted someone not cleaning up after them .
