Profound Sound

(My stepbrother has just gotten married. My sister and I, along with our respective boyfriends, are in the airport waiting for our flights back home. I haven’t slept well the night before, and am now barely conscious, so I’m napping on one of the airport couches. My sister is chatting with her boyfriend when I feel the need to interject.)

Me: *rudely* “Bleeeeeekh!”

Sister’s Boyfriend: “Hey, she makes weird noises, too. You really ARE sisters!”
