These relationships can be fulfilling in their own right, but what if you want to turn a casual acquaintance into a true friend?
Friendship is characterized by intimacy. True friends know things about each other: their values, struggles, goals, and interests. If you’d like to transition from acquaintances to friends, the best way to do so is to open up to the other person. You don’t have to reveal your most closely-held secret. Start small with something a little bit more personal than what you normally discuss and see how the other person responds. Do they seem interested and receptive? Do they reciprocate by disclosing something about themselves?
