I feel the need to vent...

[Headshrinker]

There is a classic car restoration shop within several miles from my home that often has some pretty exotic cars parked outside within feet of the road. Today, I saw a beautiful Rolls Royce outside from the 1930s and wanted to take a picture of the grille with my Rolex Day-Date to show fellow TRFs. To make a long story short, while I was taking the picture from the sidewalk, the owner came running out and began yelling at me. I tried to explain why I was taking a picture, but he told me to give him my phone to erase the picture. I told him I was a simple doctor that wanted to take a special picture. He went on and on about how the picture will probably end up on an auto internet site, and he still wanted my phone. Since I was on a public sidewalk, I told him to go f*** himself! and walked away.
I don't know if it was his demeanor or my reaction to being yelled at after spending years of sacrifice to gain the respect I feel I have earned. (Or maybe I was mad, because I felt like punching him in the mouth.) Was I over-reacting?
