So is it MMMB's advice that if I'm told "I love you" on Sunday I should respond with "I know"?

I'm pretty sure the correct response is "okay, in that case I will go ahead an loan you my Amazing Spider-Man MMW volume 1, but I won't loan you the dust jacket in case that rips, and please make sure your hands are clean before you read it and please make sure it is returned to me in the same condition that I loaned it to you."

That will win her heart!
