Here’s a foolproof method for generating the warm-and-happy-fuzzies:
Play all available versions of Have Yourself a Merry Little Christmas (preferably at least ten versions, including the ones by Michael Bublé, Karen Carpenter, Nat King Cole, Johnny Mathis, Frank Sinatra and Rod Stewart). Start singing along in the second round. Create an interpretive dance in the third round.
If that doesn’t work, you are clinically depressed.
Have yourself a merry little Christmas everyone.
