When I was little, vans all had those metal ladders on the back and a luggage rack, with metal railings, on top. I believed there was a swimming pool on top of the van. A swimming pool was the only place I'd seen ladders or railings quite like that. (Plus, I was obsessed with pools in the first place.) I remember staring very hard at vans in front of us, hoping to see a little water sloshing out.
My mother tried to tell me the truth, but I didn't want to believe it. I wanted to ask some van owner to let me climb up and at least see if there was a pool up there, but it never happened.
