I think this is a curious reaction of the mind/brain when two unrelated fields of memories are jolted together.
I remember at the 1958 Yankee stadium sessions, in a foreign language section, a brother turned red and white in shock, terror seeing me. ... he had courted my beautiful fleshly sister (prior to both him and me converting and moving, losing contact.) He just could not fathom that we were now in this new common relationship, called "truth" panic attack.
faces? then it was the 2 stroke, now it is the diesel, made in germany. ha ha the smoke is no joke.
