I cut a watermelon in half, and then Isabella and I finished the flesh of each half. When I asked her to throw away the leftover watermelon's rinds, Isabella said It was watermelon skin. I knew the whiteish part between the red flesh and green skin was the rind, but in this case, I didn’t peel the green skin off, so it was attached with the rind. Should I say please throw away the watermelon rind or skin?
