The lending of an item between friends. Similar to a rental it is understood you only keep what you received for a specific period of time. Unlike car or movie rentals friendtals have no late fees. Without late fees sometimes the friendtal becomes what is similar to theft or indefinite borrowing. as the receiving party never gave compensation for what they received.
