“However, not everything that can be counted counts, and not everything that counts can be counted.” – William Bruce Cameron (Informal Sociology: a casual introduction to sociological thinking – 1963, Random House)

If you were sole driver of a car pool – your friends would share expenses
If you invited friends to stay in a rented condo on the ocean or in Italy with you – your friends would share expenses
If you needed part of a liver or a kidney – your (matching) friends would share theirs

“. . . .  that’s what friends are for” – Burt Bacharach
