Returning What’s Yours
Being polite will only get you this far in life. Sometimes, you just have to take it up a notch and give the other person a taste of their own medicine. This OP got tired of finding their upstairs neighbor’s cigarette butts on their balcony all the time.
After repeatedly asking them to be careful, they decided to simply return what rightfully belonged to them. They put all the butts in a clear bag and taped it to their front door. If it was us, we would have simply left it all on the floor so they could clean it up and realize how annoying it is.
