" A deep friendship can keep a partner from jumping to negative conclusions when another partner says or does something that sounds derogatory and hurtful. It may be a wellspring of trust, a key ingredient of successful partnerships. True friendship can help one partner to be understanding when another has family problems that wind up shortchanging the business for an extended period of time. A strong bond of friendship may be a sign of shared values and can be the glue that holds partners together when the business is under stress. "
