Let me give you a story that will help you understand. A good friend of mine was called to a leadership calling in the ward. He mentioned that having accepted that calling made him a better man. I asked in what way he was referring to. He said now that he was in a leadership position and getting calls to help others regularly at potentially any time that he treated his wife better and was kinder to her because he knew he could have some woman call and complain about her husband doing something like what he might have just done to his own wife. So he had to be better so he was prepared to help those that needed it, whenever they needed it. He was letting his Priesthood calling have a good influence on him by letting it influence him for good.
The lesson in Priesthood reminded me of a time when I learned an important lesson from a situation that was a little tense but seems funny as I look back on it. When I was young, it was my Father's and my practice to often purchase some fries from a fast food place when we were out doing things together. Dad might be driving me to an activity or we might be doing some errand or whatever. This particular night he stopped at a place close to home and gave me a twenty dollar bill to pay for the two fries I was to order. I ran in and ordered and it seemed they were a bit slow. That was notable because I knew my Dad had little patience for being slow. But after they took my money they became really slow. I begin to get concerned that Dad would be pretty irritated. I noted they took the bill to the back and being young I had no idea what was going on or what to do about it. Finally after what seemed a long time the guy came out and gave me change and explained they thought the bill was fake and that was why it took so long. My Dad was indeed irritated despite, or perhaps because of my explanation. As we pulled out of the parking lot he said something like, "I hope they close down!"
