Bonsai tree

From emailing:

My friend wants his girlfriend to get a bonsai tree for their new home. How can he talk her into it?

He goes out and gets a bonsai tree for the house and waters it himself, but lets her admire it from time to time.
He could also bring her the beauty of bonsai, by showing her some amazing pictures of bonsai which he adors most of all or/and try to involve her to admire when he is working on it.
