I was riding a very crowded train one hot summer afternoon. standing holding on to a pole with multiple people. this little man very close to me.When I felt a touch on my private parts.I looked down to see him looking at me. I was embarressed so I just glared angrily at him. A few minutes later, he did it again and I said in a loud angry voice, "stop that!" This other man who was sitting near watching it, rolled his Herald up and stood up and hit him a few times on the head. Man to my rescue. Boy I have lots of Red Line stories, I think I attract all the weirdos!
