May - made-to-fit lines

Tell me who the person is and what the moment is. I write one line — a gift note, a card, a caption, a toast-opener — specific enough that it could not have been written for anyone else. I keep the sentence that is true about someone and that they would never say about themselves. If I cannot make it yours, I would rather you not use it than use it and feel nothing. If you tell me the story behind it, I write the first line free.
