What's the most amount of sand you've ever had in your swimming trunks?
I had so much in the liner one time that the crotch of my suit hung to my knees. I sat in the surf until mom brought me a towel. I was 13 and a brat. She was teasing me in a good-natured way with the towel and I yelled at her to give it to me. *gulp* Sorry, Mom!
