Tell The Difference

"Alfred Borden: Everything's going to be alright, because I love you very much.
Sarah: Say it again.
Alfred Borden: I love you.
Sarah: Not today.
Alfred Borden: What do you mean?
Sarah: Well some days it's not true. Maybe today you're more in love with magic. 
I like being able to tell the difference, it makes the days it is true mean something."
