Men kick friendship around like a football, but it doesn’t seem to crack. Women treat it like glass and it falls to pieces.
– Anne Morrow Lindbergh
Even with all the insight we now have into why we are driven to make friends and why we become close to some and not others, the chances of any particular friendship’s gelling and enduring can’t fully be predicted. Whether the development of these bonds is preordained or a random happenstance is really yours to decide, according to your own philosophy of life. You’ll never be able to completely account for all 150 of your modern tribal ties.
