Will you convince me to climb Angels Landing the next time around?
Will you go to a Passover Seder at Etz Hayyim in Chania, Crete?
Will you run a marathon with me? (Or how about couch to 5k?)
Will you be a vegetarian with me? (I do make exceptions: trying a local favorite while traveling and during some Jewish holidays.)
Will you challenge me to be my best if I challenge you to be your best?
