I learned how to be a nice person even when I get rotten customer service.
I learned how to laugh when some idiot cuts in front of me and I have to slam on my brakes.
I've learned to laugh when a big huge piece of farm equipment is in front of me and there is no exit for driving back country roads to get to my next location.
I've learned not to correct one of my favorite sales representatives when she calls me Mister. She has language issues.
I've learned, which I should have known to begin with...do not tell the dogs who are K-9, they are pretty dogs. (you had to be there, the dog was ready to load up)
I've learned from observation, being nice to the Border Patrol guys is the same as being nice to the Custom Agents at an airport. Snotty, you will be detained. They are only doing their job, let them do it.
I've also learned that my ability to speak Spanish needs extensive work. Don't use Spanish in my jobs, but it would come in handy at convenience stores when I'm working.
Live your life in such a way that when your feet hit the floor in the morning; the devil shudders...And yells OH #%*+! SHE'S AWAKE!
