hmm... I think I did a show and tell with an old FM system in preschool, but I have no memories of it. I just remember a picture where I seem to be demonstrating my FM system. But in 9th grade I gave a speech on the history of hearing aids, and in 12th grade, the senior groups all did the problem that I created on cochlear implants (this was my way of educating others on deafness and of ways to help the deaf with CI's or hearing aids, etc.). And when I got my purple hearing aids in 3rd grade, I showed them off (but not show and tell) just because I was proud of them.
