Don't feel bad, I got a ticket the day I picked up my wife and new born Baby from the hospital.
I was parked in the traffic circle out front, which is for loading and unloading passengers. I went inside the hospital to pick up my two passengers.When I came back outside, I see a Parking enforcement officer writing someone a ticket. Hmm, now that she is finished writing the ticket, why is she standing next to my car, she patiently waited for me to load the flowers, my wifes bag and while I got the car seat and new baby in the truck. She even waited while I strapped my 2yr old into the other seat.

As I walked back around to the drivers side, She says "here ya go", I say your kidding me right. She says, "well your vehicle was left unattended, so heres your ticket". I actually had to laugh.
The kicker, as some of you know I'm a police officer, she worked for the same department as me. Yes, I took the ticket, enjoyed the rest of the day with my newly expanded family and paid it when it came in the mail. Life's to short to sweat the small stuff.
