Grandma:...and I always fold the sheets army style...
Johnny:Uh, huh.
Grandma: That way they look good the next morning no matter what kind of hanky-panky has been going on.
Johnny: And what about these pillow cases?
Grandma: Well, after you wash them and press them, just stick a pillow in 'em.
Johnny:Like this?
Grandma: That's upside down! Can't you get anything right?

奶奶： 洗过烫平之后，你只要塞一个枕头进去就好了。
