If you steal someone else's Tupperware, that's all I need to know about you!

There's always that one thing that a person does that makes you say "that's all I need to know about you!" including but not limited to, "borrowing" someone's Tupperware and trying to pass it off as your own or ringing a doorbell a second time when you can see someone is coming to the door only to tell you they're not interested in whatever you're selling.
