The man who promises everything is sure to fulfil nothing, and everyone who promises too much is in danger of using evil means in order to carry out his promises, and is already on the road to perdition.
To promise not to do a thing is the surest way in the world to make a body want to go and do that very thing.
Sometimes people don’t understand the promises they’re making when they make them. Right, of course. But you keep the promise anyway. That’s what love is. Love is keeping the promise anyway.
