Ah yes, channeling your inner child and splashing around for a few minutes after (or before, or at intermission!) a performance on a hot summer night is definitely refreshing! Barefoot isn't required though, my wife headed right in in heels, beckoning me in behind her. By the time we finished with our playful splash fight, my dress slacks were soaked and water was dripping from the hem of her soaked cocktail dress.
You have to grow older, but you don't have to grow up! Enjoy life, don't be afraid to be a little wild and crazy!
