Not like what you think.
I almost drowned when I was five.
I swam like a little fish by that age. Jumped or dove in fearlessly.
This time, I fell off the end of the dock.
I still remember tumbling upside-down, the sensation of breathing water into my lungs and hearing myself cough underwater.
I couldn't stand up. I couldn't get my bearings because I didn't know where "up" was. I couldn't get to the surface to take a breath. I couldn't reach up to grab hold of anything in order to pull myself back on the dock.
My grandmother was sitting a few feet away. Probably knitting or reading a book.
If my grandmother hadn't seen me, if she hadn't come to the end of the dock and hauled my little tush back up, I wouldn't be writing this today.
Drowning looks like THIS.
Read it, remember it.
