Two incidents from before my memories.
I mentioned I was a climber. I think I was two. Dad had a razor with individually-wrapped blades that came in a little box. Mom walked into the bathroom, and found that I had gotten onto the counter, into the medicine cabinet, and taken one out. I was about to put it in my mouth. I showed her, very proud of myself, and said, “Gum!” Fortunately, she was able to grab me just in time.
The other time was, I think, in a movie theater. I decided to rummage through the purse of the lady next to me. Apparently, a product at the time was hair dye in capsules. Which looked like candy to me. They only knew I’d been eating them when they saw my face stained with the color. I had my stomach pumped.
