A childhood belief about places

When I was a preschooler, my parents talked about "going to visit Miami." I did not realize "Miami" was a city in Florida, so for a long time I thought an "ammy" was another kind of relative, like a grandma or a cousin or an uncle. I kept asking them, "who's MY ammy?" and they didn't understand what I meant until, exasperated, I yelled, "well if YOU have an ammy that means I probably have one too!" Then they explained it to me. ;-p
