One small incident, indicative of Ann's attention to, and consideration of, others:

A few years ago, Ann and I and a few others were crossing a bridge over a river somewhere.   Acrophobic when more than three inches off the ground, I began wobbling and was unable to walk.  Ann saw what was happening to me, said "Let me help you," grabbed my arm, and escorted me safely and happily across the bridge.  No one else we were with had any idea of what had happened, and Ann and I never spoke of it.  But I'll never forget Ann's thoughtfulness.
