I have had a few friends from work say, oh that's nasty. There's duck poop and everything on the roads in the park. I respond with that's what a shower is for when I go home. But, people's hands are far nastier, for example. I will see guys use the bathroom and not wash their hands, rub their hands all over their face, and rub their eyes', and wipe their mouth off from tobacco, and handle door knobs from others' who haven't washed their hands either, and then I say my feet go no place near my mouth, and your argumment is? Of course no comment is made after that issue is brought to their attention lol.
