I just remembered another story from when Dad was in the Emergency Room earlier this week…
The doctor, when doing his initial assessment, asked Dad to raise his right arm. Dad raised his left arm.
The doctor smiled and looked at us, then said “okay, now can you raise your other arm?”
Realizing that he’d raised the wrong arm the first time Dad said “okay, but only if we can call it the left one.”
The doctor, Mom, and I laughed. The Doctor said “sure, works for me”.
