Boy’s sister: who are you on the phone with?
Boy: just one of my friends.
Boy’s sister: don't lie to me.
Boy: why would I lie?
Boy’s sister: is it that girl you never shut up about?
Boy: no! It’s one of my friends!
Boy’s sister: you liar. I know it's her. Whenever you're on the phone with one of your friends, you make fun of him, he makes fun of you, and then you both laugh. When you're on the phone with her, you just sit there trying to be cool with a stupid smile on your face. :) ♥ :)
