“College students” and “Teenagers” two of my most HATED “Groups”...now get the HELL off of my lawn!
There’s an iPhone/iPad app called “Get off my lawn”.
It plays an annoying tone that only young people can hear.
My husband and I cannot hear it, and we play the app when we want our teenagers to leave the room when we are watching TV.
We have a lot of fun with the app.
