I saw this guy attempting to suck his dick and for some weird reason I had to ask him what he was trying to do. The guy looked at me semi-angrily and said; "I'm trying to mind my own business, how about you?" I didn't even answer, I just couldn't, and I felt so embarrassed, not because he was sitting right next to me! But because he was absolutely right. He was minding his own business. So I just resumed reading my book and waited for the train to arrive at my stop.
