He knew that 'I love you' also means 'I love you more than anyone loves you, or has loved you, or will love you,' and also, 'I love you in a way that no one loves you, or has loved you, or will love you,' and also, 'I love you in a way that I love no one else, and never have loved anyone else, and never will love anyone else.'
You can sit beside me when the world comes down, If it doesn’t matter then just turn around. You be the queen and I’ll be your clown; You can sit beside me when the world comes down.
