Goodwill resembles friendship, but it is not the same thing since it is possible to feel goodwill toward strangers or people who are unaware of one's feelings, while friendship would be impossible in such circumstances. Goodwill also differs from affection because it does not have the same intensity and can arise on the spur of the moment. Generally speaking, goodwill can be defined as an inactive or potential form of friendship. It can develop into actual friendship after a period of time in which familiarity between the parties increases. As a rule goodwill is created by admiration of some fine quality in the person toward whom it is felt.
