Just once in your baseball experience, learn to umpire. Go to a local umpire board and tell them that you want to umpire for the season. They'll schedule you with an upcoming class of others similar in interest and limited experience, and off you go.
You'll learn the two umpire system, umpire equipment, the rules of the game - tailored to the amateur rules of the leagues that you'll cover, and other need-to-know stuff.
Usually these classes are held in the winter months, in a hall, classroom, municipal or town meeting room, and so forth. You'll get material to study and exams will be scheduled along the way to see if you're retaining what's being taught. You'll also develop a deep respect for this part of the game and you'll appreciate a totally new outlook about the men and women who are the official representative of baseball.
After a season or two, I guarantee you that you'll think twice before hammering the guys & gals who call fair and foul, safe and out, balls and strikes.
I coached with a first base coach who was about as obnoxious as they come, especially to umpires. No matter what happened, by who, when and why, there was always a negative remark coming out of this guys mouth. He got called for jury duty and was gone for about two weeks. Upon returning, it was like we had a different man on our club. He was reserved, he was polite, he was anything but what he was before he left. Why? Well, during his jury duty, he was elected Jury Foreman. As it turned out, he had a room full of people just like himself to deal with. A reality check to be sure.
