What is friendship to you? Friendship means different things to different people, and there are many different categories of friends. A quick Google search describes categories of anywhere from 4 to 14 different kinds! I think I’ll stick to the simplest list of 4 types: Acquaintances, Casual friends, Close friends, and Intimate or lifelong friends. Although each category has different expectations attached to them, it’s important to be able to recognize the behaviour of a true friend, and one who is not.
