Have you ever been in a public restroom and worried that someone might walk in on you while you're squatting? Chances are that's probably happened to you. A similar thing happened to me recently during one of my ultrasounds.

San Francisco's latest and greatest perinatal clinic is fabulous — beautifully decorated with state of the art technology and highly esteemed professionals.

Since the room was dark, it took him a minute to register that he was lost. I piped up, "I think you're in the wrong room!" Clearly, I knew, not thought, he had taken a wrong turn.

The technician apologized profusely claiming that never happens. I said, "I'm sure he is ten times more embarrassed than I am at this point. He's probably heading for the hills right now." Having been exposed to a crowd of doctors and nurses in a delivery room, this was the least of my concerns. I dare say I found it funny.
