It is really hard to surprise Jeanine. This evening, I took her out on a mystery date. Open-air dining at Bistro 781 in Waltham where they have closed Moody St. to traffic and all the restaurants there have set up tables outdoors. As we approached on foot after parking where we could, it was no feat of detective work to determine that we were going to have dinner al fresco. As we approached the restaurant, Jeanine asked me if we would be joining good friends, Tom and Karen Metzold for dinner. How could she possibly know this? Apparently, she pattern matched the last time we dined in this area with the time of year and made the correct prediction. Even though she ruined the surprise, it did not diminish the enjoyment we had catching up with my high school wrestling partner and long time friends.
