It was around 1973. I was working at Planned Parenthood HQ in NYC.
On the elevator ride up to my office one morning, there were two guys having an esoteric discussion about the use of a particular word, or it might have been about using one word vs. another. I thought to myself something like: Imagine that, having an entire discussion about a word. These guys must be editors, and this is what they do for a living.
That was the first time I even thought about editing and editors. And here I am 37 years later and into my 27th year of editing.
