This is a true story. My younger brother is a computer programmer. He is good at what he does. He even has written a Amazon top selling book on it. About 8 years ago someone was exceedingly rude to him on a chat room. My brother is a mild mannered polite guy. He is not a Christian, and I wish I had his temperament. So anyway, he says to me enough is enough with this guy on line. I am going to use my computer skills to track him, and I am going to write him a letter saying maybe you would not be so bold and rude if you were not hiding behind a computer. And about 3 days later he gets the info, and he can't believe it, the guys lives like a hour from him. So he says to me he wants to go knock on his door, not to start a fight, but to just say to the guy I am the one you talked so rudely to, now please say it to me in person I will respect you more if you do. And my brother asked me to go with him, just in case. I tried to talk him out of it, but not good.
So anyway we go, and the guy was stunned, it took him about a minute to get his composure, and could he not apologize enough. Completely different tune in person.
