A woman named Emily renewing her driver’s license at the County Clerk’s office was asked to state her occupation. She hesitated, uncertain how to classify herself.

“What I mean is,” explained the recorder, “do you have a job, or are you just a …”

“Of course I have a job,” said Emily. “I’m a mother.”

“We don’t list ‘mother’ as an occupation… ‘housewife’ covers it,” said the recorder.

One day I found myself in the same situation. The clerk was obviously a career woman, confident and possessed of a high sounding title. “What is your occupation?” she asked.

The words simply popped out. “I’m a Research Associate in the field of Child Development and Human Relations.”

The clerk paused, ballpoint pen frozen in midair.

I repeated the title slowly, then I stared with wonder as my statement was written in bold, black ink on the official questionnaire.

“Might I ask,” said the clerk with new interest, “Just what you do in this field?”

Coolly, without any trace of panic in my voice, I heard myself reply, “I have a continuing program of research (what mother doesn’t), in the lab and in the field (normally I would have said indoors and out). Of course, the job is one of the most demanding in the humanities (any mother care to disagree?), and I often work 14 hours a day (24 is more like it). But the job is more challenging than most careers and rewards are more of a satisfaction rather than just money.”

There was an increasing note of respect in the clerk’s voice as she completed the form, stood up, and showed me out.

As I drove into our driveway, buoyed up (受鼓舞) by my glamorous new career, I was greeted by my lab assistants---ages 13, 7, and 3.

Upstairs I could hear our new experimental model (a 6 month old baby), in the child-development program, testing out a new vocal pattern.

I felt proud! I had gone on the official records as someone more distinguished and indispensable (不可缺少的) to mankind than “just another mother.”

Motherhood…What a glorious career! Especially when there’s a title on the door.
