So, Natalie fell asleep at a graduation party at Sarah's house, and then something funny happened! Natalie started to snore. You see, snoring is when someone makes a funny noise while they're sleeping, kind of like "zzzzz" or "hhhhhh". So while everyone else at the party was still awake, Natalie was making these silly noises in her sleep!
