20s-something woman: Oooh, it’s totally going to rain on us! Look at those clouds.
20s-something guy: No, those clouds are moving east; away from us. We’ll be fine.
20s-something woman: What? Clouds can’t all go in the same direction! They’re floaty. They float around. Some could come here.  How would they know to all go one way together?
20s-something guy:  Wind. It’s called wind. Are you joking?

Overheard by but how does the wind know which way to go?
