It was a deep and profound eye opener for me to (1) notice how most of the writing about the stuff I did all day was written specifically for people without Y chromosomes
but more importantly
(2) it made it much more clear to me what it must be like to be a woman who wants to be or is a part of a male-dominated field. Even though I was already aware of the concept of gendered literature as it pertains to a field of endeavor, wow, was it a totally different experience to have it apply directly to me and to my feelings. I used to be a bit cavalier about this - acknowledging that it was a real thing, but downplaying its significance.
No more. The kid is now 25, and we talk gender politics every other week :)
