Photo: The father/daughter kiss that's got people talking

So this is a pic of a father and his grown daughter kissing on the lips. That's Bill Belichick, the head coach for the New England Patriots of the NFL. He celebrated by kissing his daughter Amanda on the lips after his team won the NFL Super Bowl last night. Most people thought the kiss was too intimate and too weird. Many said it looked like they were making out. What do you think? Should parents be kissing their adult children on the lips, in public? You find this weird?
