Stumbling on Happiness

• Why are lovers quicker to forgive their partners for infidelity than for leaving dirty dishes in the sink?
• Why will sighted people pay more to avoid going blind than blind people will pay to regain their sight?
• Why do dining companions insist on ordering different meals instead of getting what they really want?
• Why do pigeons seem to have such excellent aim; why can’t we remember one song while listening to another; and why does the line at the grocery store always slow down the moment we join it?
