If a thing is lent for use for a specified time or purpose, it must be returned to the lender without demand, as soon as the time has expired, or the purpose has been accomplished. In other cases it need not be returned until demanded. The borrower of a thing for use must return it to the lender, at the place contemplated by the parties at the time of lending; or if no particular place was so contemplated by them, then at the place where it was at that time.
