My third grade school picture, 1983.
What is even that expression lol? I have no idea. "I've got a silly secret!" And that secret is that my two front teeth have come in and they're too big for my mouth!
[Please share your own throwback pix in comments. Just make sure the pix are just of you and/or you have consent to post from other living people in the pic. And please note that they don't have to be pictures from childhood, especially since childhood pix might be difficult for people who come from abusive backgrounds or have transitioned or lots of other reasons. It can be a picture from last week, if that's what works for you. And of course no one should feel obliged to share a picture at all! Only if it's fun!]
