Wallace Stegner said this quote
“ Touch. It is touch that is the deadliest enemy of chastity, loyalty, monogamy, gentility with its codes and conventions and restraints. By touch we are betrayed and betray others ... an accidental brushing of shoulders or touching of hands ... hands laid on shoulders in a gesture of comfort that lies like a thief, that takes, not gives, that wants, not offers, that awakes, not pacifies. When one flesh is waiting, there is electricity in the merest contact. ”
