As somebody who grew up wearing hearing-aids, the real world is unfortunately nothing like what you describe especially with younger kids (although I agree it would be lovely).
Also, you might want to tone down the mocking just a notch (that, or I'm reading too much into your tone, possibly due to my experiences).
Kids will mock you, or try to yank on them. Or when you lose them, it's funny. I used to use behind-the-ear ones, and then switch to in-the-ear aids, to be less visible.
In the words of Mark Twain - "Human beings can be awful cruel to one another".
Now that I'm older, I tend to only use them in a work context - in social settings, I tend to prefer 1:1 meetups anyhow, which makes it easier (you can lip-read easier if it's just one person at close range).
For work, people are professional, and you can trust that it's fine. And look, honestly as an adult, you assume other adults are reasonably mature and won't judge you just because you have a disability. But yeah, for children, that unfortunately doesn't always hold true.
I've actually switched to behind-the-ear again - simply because the sound quality is better, in particular the directionality.
