The Post Traumatic Stress Disorder (anxiety) you experience after finding multiple or successive tickets in your mailbox for speeding and/or traffic light violations. This can happen when you are visiting a new city or area of town, and you don't know where the traffic cameras are poised to "nab" you.
Sister 1: I have a bone to pick with you.

Sister 2: What?

Sister 1: When I went to my mailbox Monday, there was a ticket for $75 from speeding on Michigan Avenue during my visit to see you in DC. We don't have speed cameras in Atlanta, so I thought, "What is this??"

Sister 2: Ooops. I forgot to warn you about those cameras.

Sister 1: Then, I went to my mailbox on Tuesday, and there was another $75 speeding ticket! They caught me both coming and going on Michigan Avenue!

Sister 2: Oh no!

Sister 1: On Wednesday, as I approached my mailbox, my heart started racing, and my hands were shaking! Going to the mailbox is now traumatic for me.

Sister 2: (Gasp!) I am so sorry... you have symptoms of Mailbox PTSD.
