I've just replayed (in my mind) your visit here with young Harrison..as you played piano and he worked on puzzle I gave him I recall him using his left hand much of the time..
but I was so taken with his dialogue/wit and questions etc. I didn't pay much attention..
Left handed piano - yes I have one - you were playing it..we can work on price..100 yr. old Heintzman..dust collector..
