This week, in anticipation of Father's Day, HuffPost was full of Dad-related content of all sorts, from gift ideas (believe it or not, some dads are hoping that package the kids left waiting for them on the kitchen table contains nose clippers) to moving accounts of losing -- and finding -- a father. Though, like any holiday, the day often comes with its share of pain - for fathers who have outlived their children, especially -- the opportunity to hear men articulate the unexpected ways parenting expands a life somehow makes the pangs of sadness (not to mention the awful greeting cards) worthwhile. What's the best way to fete a father today? Buy him a book? Turn his old tie into an iPod cover? Pump him for information on the family's medical history? Any of these might work, depending on the dad, but ultimately it's the quiet celebration of an authentic child/father connection that's most important. Which means: The perfect Father's Day gift is far more likely to be the heartfelt hug, handshake, or cuddle that evolves organically with no help from Hallmark -- or even HuffPost.
