"Peanut butter."
"Chocolate chip."
"Peanut butter!"
"Chocolate chip!"
"Emily, everyone knows that peanut butter cookies are far superior to chocolate chip."
"Spencer, everyone knows that chocolate chip cookies are the best cookies in the universe."
"You're only saying that because you're PMSing and craving chocolate. If you were thinking straight, you would agree that peanut butter are the best."
"Reid. Spencer. My love muffin—"
"Love muffin?!"
"— I deeply adore you, but the next time you blame my period for my love of chocolate, the only body part of mine that you will be eating is my fist."
"Love muffin? Seriously?"
"Shut up and grab the chocolate chip cookies."
"But peanut butter are better!"
"Oh for god's sake." Two packages of cookies were tossed unceremoniously into the cart.
Grinning widely, the two arguing adults called, "I love you, Hotch!" to their mutual lover, watching his ears turn red as he walked away.
