There was another remarkable thing about John. If anyone came to borrow something from him, he did not take it in his own hands and lend it, but said, ‘Come in, take what you need.’ When a borrower brought anything back, John used to say, ‘Put it back where you found it.’ If a man borrowed something and did not bring it back, John said nothing to him about it.
