A handshake, a hug, a high five, a fist bump. All of these gestures are a way for a father to let his son know how much he loves him. And over the years, it’s these gestures your son will remember as a sign that you care. This year, send a birthday card that will touch his heart and remind him that no matter how old he gets, and how far away he is, you’ll always have a one of the most special bonds, and that’s something he will treasure forever.
