It just makes you want to make them miniature-sized and put them in your pocket...

I saw the CUTEST old couple (old means late 60s, early 70s) on the metro on the way home. They were all dressed up -- obviously having either had a big day or night on the town -- and they were just so adorable. The wife hustled her husband into the metro car and kind of directed him toward a seat and they just kept whispering like little kids the whole way home. Precious!
