In grade school, one of my male science teachers was very effeminate, and he was something of a laughingstock because of it. I never saw him act inappropriately with any students, neither was i aware of any rumors that he did so. Nevertheless, students outside his class mocked him because of his mannerisms.
Fast forward ahead by fifteen years. I was coaching a group of junior high schoolers, and I overhear them mentioning one of their science teachers of the same name. Could it be the same guy? Unlikely, I thought. The kids attended a strictly Catholic school (not the same school I attended), and it seemed unlikely to me that this school would hire someone who was so flagrantly effeminate. Besides, the kids were discussing the content of the course, not the mannerisms of the teacher.
But I asked the kids anyway.
"You know, I had a science teacher named Mr. ____ when I was your age," I said. "But I don't think that your teacher and my teacher are the same guy. The teacher I had, well, he acted... you know.. like he was gay."
All of the students' faces lit up and they broke into laughter. "That's him!" they all said. They were apparently not permitted to speculate openly about his sexual orientation, but it was quite clear that they did so in private.
