I was a fairly new Trooper sitting in the court Bailiff's office, at one of our courts, waiting for one of my first trials with an actual defense attorney involved. This particular defense counsel was well known for attacking the arresting officers actions, character, training, parenting and anything else he could get by with to try and get the officer rattled. There was another older officer (Shotzy) from another agency in the room waiting for his case to be called and he told me to stick my hand out and he took out his pen and wrote DLTSOBPYO on my palm. Shotzy explained the abbreviation stood for, Don't Let The *** P... You Off and whenever opposing counsel starts to get under your skin, just look down at your hand take a breath, grin and relax. It worked and it threw the attorney off "his game" and took away one of his favorite "tactics".
I also learned that when I was about to go up against this particular attorney on a case and I ran into him in the court hallway before trial, I would greet him like we were old friends, shake his hand and it seemed to tick him off a good bit.
