A very early memory

I have wet myself for as long as I can remember. One early memory, I was 7 or 8, I had a playmate, we were in my back garden, I needed to pee. I was wearing short trousers. I didn’t want to go into the house so wet myself in front of my playmate. I remember telling him it wouldn’t take long to dry. I guess I must have done it previously to know that! We then just carried on playing.
