Has anyone ever yelled at you?
Man, I’ve been yelled at quite a few times by quite a lot of people. At the time, the drama makes what they are yelling seem really important. More often than not, the yelling is just the yellers way of getting you to do what they want you to do. They lack the ability to formulate a compelling argument, so they try to force their way with, uh, force.
Yelling back only escalates matters. That isn’t a suitable solution.
So, ignore the yellers.
Unless the building is on fire.

Very good advice. That is what I do at work, ignore and concentrate on the task at hand.
