Dear Calculus,
Be my Valentine. I don’t understand everything about you, but every day I am more and more struck by your unusual beauty. I’m not perfect, and even though I try to answer all your questions, I know sometimes I will fail. You give me a headache some times, with all your rules and unknowns. But I will still keep trying because you are beautiful and worth it to me.
With love,
Your ardent student
