Friends are people who go on conspiratorial shopping sprees together, diving in and out of shops totally beyond their price range, and ending up eating oozing cream cakes with only just enough money to get home. A friend never mentions a thing to the old blabbermouth over the road. Acquaintances call nervously to ask if they can do anything to help. Friends come and sit with your horribly infectious kids while you dash off to the concert. It's easier to love mankind than to keep a few friendships in good repair.
Love links two lives inextricably, like Siamese twins.
Friendship lets you walk comfortably side by side.
