I had a guy pull along side a while ago in a convertible and I thought he was talking to me, so I yelled in a winded tired voice (louder than I expected), "What did you say?" Turned out he was on the phone and the ear piece was in the side I could not see. So I mumbled sorry I thought you were talking to me. It was like high school all over again.
I just assumed he was berating me for being in the road and in the left turn lane; I stereotyped him and was woefully wrong.
