in hockey, a hat trick occurs when a player scores three goals in a single game. legend has it that "in the 1940s, a Toronto haberdasher used to give free hats to players with the Toronto Maple Leafs when they scored three goals in a game, which introduced the "Hat Trick" expression into the world of hockey." today, when a hockey player scores three in a game, fans would throw their hats onto the ice to honour such player's feat.
I just saw the tip of the first hat and knew instantly it was your photo! It's a fabulous composition and so thoughtful of you to honor your dear friend this way! Also very interesting to know the origion of the phrase!
