Motherhood Is a Career to Respect

A woman renewing her driver’s license at the Country 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(研究员) in the field of Child Development and Human Relations.”

The clerk paused, ballpoint pen frozen in mid-air.

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

“Might I ask,” said the clerk with interest, “just what you do in your 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 laboratory 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 the 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(激励) 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.
