Step-by-step explanation:
Friends are people who we are not related to but choose to interact with.
Family relationships are ideally life-long, although as children become
teenagers and then adults, it is usual for them to have more
independence and for the parental relationship to become less one of
guidance and more one of mutual support.
A lover relationship is one in which you feel very strongly attracted to
the other person, both to their personality and, often, also physically.
This is reciprocated by the other person in the relationship.
