sad experiencing or showing sorrow or unhappiness; "feeling sad because his dog had died"; "Better by far that you should forget and smile / Than that you should remember and be sad"- Christina Rossetti

Pensive (1941-49) was a bright chestnut thoroughbred racehorse who in 1944 came closer than any other horse at the time to winning the U.S. Triple Crown. He was also the first to win the first two legs and then lose the third. A son of England's Hyperion (who himself had won two thirds of England's Triple Crown), out of Penicuik II (by Buchan), Pensive, ridden by Conn McCreary, won the Kentucky Derby going away by four and a half lengths.
