It is a complex undertaking; placing your friends under such a lens. To aid you, the novice FriendChartographer, in determining who your true friends are and trimming the acquaintances who haven't made the appropriate effort to earn the moniker of "FRIEND", I've put together a brief tutorial of the FriendChart Basics.
Advanced FriendChartography is no simple task. But fear not. You can start small and work up. You shouldn't expect to be and expert at the outset.
The FriendChart is based on a simple five finger rule. This rule is founded on the philosophy that each of us has five fingers (when you completely disregard one of your hands) Thus you have room for exactly five friends.
Each finger has a value, and thus your friends can be ranked in relations to their importance in your life.
Take the Index and Middle fingers for instance. These are your two best friend fingers. The FriendChart allows for up to TWO unranked best friends. Best friends are a very special commodity, and as with any precious possession you should always have a spare. These friends are good alone or as a team.
Despite his shortcomings Friend Five is as necessary as any to rounding out the group and creating a Voltronlike Flying Fist of Friendship Fury.
Now that you've got the basics go out, judge your friends. Rank them, re-rank them. Let them know where they stand, and watch as they scramble to improve their position.
