I ran into a lady I knew 20 years ago in a different job. This happens all the time and all over the place. This time she sat next to me on a flight between LA and San Francisco. We caught up in the hour we sat together. She remembered me, knew my name even. I thought she looked like somebody I used to know. She was a fat happy grandma now and a frustrated office manager back in the day.
She remarked that I had not changed much, still big, burly and friendly. I had to laugh.
