Affection is related to a type of love. It is when you feel warmly toward someone and a bond stronger than friendship. It can be between parents and children, other family relatives, partners (like husband and wife, boyfriend and girlfriend) and some friends. If the feeling is mutual, both people can express affection through contact such as kissing, hugging and holding hands. It may also be expressed though doing things for each other/helping each other through situations/being there for each other.
