LEASING is a contractual arrangement in which a party pays to use an asset owned by another party for a specified period of time. Indisbelief is the state of not believing something, usually due to lack of evidence or proof. Together, these two words represent the idea of not buying into something, either because it is not worth investing in or because there is not enough evidence to support it.
