The Door to Door to Door People

I think I was in a Dr. Sueuss novel…..In a recent doctor office visit to a new doctor, I witnessed total consummation of reality and childhood story book!

Sitting in a hall, chair against the wall, I found many travelers having a ball!
They would travel here and there and everywhere.
From door to door to door they go! How do they not step on each others’ toes?
Not five minutes it seemed to me that they would be.
Then they would leave one place to walk through to another space!
The traffic pattern was amazing! I could not help but continue gazing!
How does the front desk lady know? The timers chime and it is time to go!
