Anxiety

I went out with my best friend today. We went to subway and then to a park. But before we went to the park, some guy was being completely rude to her. I had a bad night at work with a rude customer and I guess I was just fed up. He kept saying check it out referring to her body. I stopped for a second and it just came out “Why do you have to be so rude?” He looks at me and I keep walking. He yells “I wasn’t looking at you.” I said “I know you weren’t looking at me you were looking at her.” I can’t believe I stood up for myself once, even if it was for my friend. It always happens when I got out with her, but not always that rude and obnoxious.
