Years ago, when I was at my first internship, I was having a casual conversation with a female coworker on my team. We got to know each other a bit, and then I slipped the question, "How old are you btw?" thinking it was completely appropriate given the development and length of the conversation.

Then she lost her breath and looked extremely shocked, she proceeded to bluntly tell me, "Don't ever ask a woman that again."

I hadn't realized such a basic question was such a horrific crime at the time, after all, the girls my age (17 or 18) at the time didn't give a shit about revealing their age.

The fact that such a simple question is considered the most offensive thing you could ask a woman makes me realize that women do believe the wall exists.
