I have something to tell you. Fun is not a four-letter word. But for a reason unknown to all but circus clowns and roller coaster designers, adults graduate from childhood and somehow forget everything we know about having fun. Life 101 advice: Let this summer be a time in which you remember the thrill of a tent pitched in the backyard, the joys of yelling BINGO, and the chuckle of wearing a costume when no one else is. Oh, put that silly grin on your face and play a little! Trust me, you’ll thank me come fall.
