Of course if you work with typically developing elementary school students you know this isn't the case. At least one kid in each class is going to be aware of something out of the ordinary. My first year teaching I had a student ask me, "How are you even going to get a husband if your hair looks like that?"
You know, that kind of thing. Comments your friends would find a way to point out to you nicely and your acquaintances would simply ignore.
Last week I went over to speak to a boy who was loudly whispering to a friend in line. He was very into his conversation and clearly didn't want to be bothered by this new teacher who'd suddenly showed up in his classroom. He turned to me, slightly, as I reminded him to stand quietly in line. He looked like he planned to ignore me, but then his eyes started to get big.
"Are you having a baby or something?" he asked in horror, staring straight at my stomach.
And I knew, immediately, that I was back in a typical elementary school classroom, for better or worse.
