On people throwing stuff on the ground

When I walk down the streets in my city, I cannot hide my bewilderment when I see any kind of stuff you might imagine thrown on the ground. And when I say "any kind" I really mean anything. It's not just cigarettes —I have been a smoker, it's not easy to find a place to throw the stub— or a chewing gum wrapper, not the bus ticket and not even an ATM receipt.

Don't think I am too moaner, I finally got used to slalom across rubbish and I am a master at anger management. But I wonder what would you think if you happen to discover that someone "forgot" a dirty diaper in the full city center, a juice tetra-brik or even a full dog poop plastic bag forgotten on the pavement (I appreciate the dog owner to fill the bag, I only miss a last effort, come on). And what if you see people throwing rubbish straight from the window in the middle of the street? Isn't it disgusting?

This story related by an acquaintance of mine triggered this post. He was walking on the pavement and two ladies (presumably a mother with her daughter) were walking in front of him. At a certain point, the woman lost a sheet of paper, so what would the man reasonably think? Possibly that she did not realize it had slipped out of her bag. So once he collected it from the soil, he went straight to the woman.

—Sorry, I guess this is yours, you just have lost it— he said, gently offering her the paper.

—Oh, no. I don't need it, I have thrown it away, thanks anyway— she answered sarcastic.

—I see, so do you want me to throw it for you to the nearest trash-bin?— he replied.

—Well, it really doesn't matter. At least we'll keep street sweepers busy doing something— she finally answered insolent and proud of her attitude before her young daughter.

The world is full of motherfuckers. And yes, I am totally zen.
