'What would you say if I told you I loved you?'
'Well...I suppose I would ask, how do you know?'
'How do I know?'
'How do you know that you love me? I mean, it's a big thing to say. Love is a...really important thing. Wars have been fought because of it. People have killed others and themselves for it. It's not something that should just be thrown around because of an awkward silence, or to try and get out of trouble, or used in a casual way. It's important to mean it. Really mean it.'
