revenge

The concept of respecting your elders sort of goes out the window when they go out of their way to deliberately disrespect you. This person's grandma took no effort to learn a name, and refused to get it right out of spite. It seems like the only natural conclusion would be to give her some of her own medicine. For a different direction of a grandma story, here's a cringey guy who tried to correct a Japanese grandma on her own pronunciation of Japanese.

Enough of all the landlords in the world trying to take advantage of their kindhearted tenants just trying to plant their roots. Seriously, this landlord thought they'd be able to pull a fast one on the tenant and raise their rent by $500 just because they knew the tenant had the money to pay that. Fortunately, the landlord was stopped in their tracks. 

We're talking Professor Umbridge from Harry Potter levels of toxic from this teacher, folks. Yes, by the sound of it this teacher was a disaster from the start. Fortunately, one particular student ran the issue back to the dean of the school, who intervened after assuring the student that they wouldn't have to worry about passing the class. With that kind of free (and totally warranted) pass, the pressure completely dissipated. They actually managed to have some fun with the whole situation. The lesson that the teacher hopefully learned would be to teach the actual material that the students are paying thousands of dollars to learn. 

People that have the audacity to invite themselves over, and then refuse to follow the house rules are something else. This insensitive step mom used all the water during a gnarly drought, so a glorious case of petty revenge ensued. Check out another glorious case of pro revenge with this aggressive girlfriend who had the nerve to steal from her ex's bank account.
