Shared trait

If there is a single trait that both my older brother and I inherited
from our father, it is the propensity to stop while out walking to
talk to perfect strangers.

He and I were walking this day and he introduced me to two people he
had, in turn, introduced himself to a few days before. Helen and Mike
are in their 80s and walk for a couple of hours every day that they
can. She can run a half mile. They have lived in this house for six
decades.
