My friends are NOT dispensable, replaceable commodities. I can’t just pick one off the shelf of some Friends R Us store and say to myself, “Gee, I think this one can understand me pretty well, I think I’ll get this one.” I can’t take one to a store clerk and ask if the friend comes with a lifetime warranty. Because they are NOT dispensable, replaceable commodities.
Perhaps friendship ROLES are replaceable, because those can be dynamic and aren’t always static. But FRIENDS aren’t replaceable. The way they fill those roles, the things they’ve done for you… that can’t be replaced.
