Skylerism: Patronus

S: "Mom, you can't cast a patronus. Dad can and so can I, but not you."

M: "What? Why not?"

S: "Well, in order to cast a patronus you need to not only focus on casting the patronus, but you also need to think of a really happy memory, like maybe the day you were born or something like that."

M: "I think I can do that. If both you and Daddy can do it, then why can't I?"

S: "Well, you know how--, well, you're always saying you can only do one thing at a time."
