I went to the library yesterday. I’m wearing a Beatles’ “Rubber Soul” tee-shirt. This guy comes walking toward me wearing a John Lennon tee-shirt. Lennon with the long hair and beard. Do I say something to him like, “nice shirt.” Or say, “his post Beatle career sucked.” Maybe nod to him to acknowledged his shirt.
Nope, I did none of the above. I just kept walking.
