DO NOT covet all the books inside crammed and quaint bookstores that contains volumes stacked high in irregular towers, just waiting to be bumped over by a lascivious reader—your luggage is already at the maximum weight limit.
DO stand OUTSIDE the chronometer shop as to avoid buying unneeded but absolutely necessary antiquarian brass microscopes and barometers.
DO Remain pacing OUTSIDE aforementioned chronometer shop, despite the stares of the shop owner and one patron, who wonder why you stand outside in 23 degrees of brief snow flurries like a stalker.
DO mark the chronometer shop as a favorite on the map, then proceed to forget about it while in Paris; later mourning the failure to purchase said needed instruments.
DO close out the first evening in Paris with an attempt at Clair de Lune, a steaming cup of tea while the radiators take HOURS to warm up the frozen flat, and a Korean face mask (wow, it really does erase the wrinkles at least until I wake up 13 hours later! If I could creep the mask on and enjoy my smooth skin :-) Ha!
DO partake of cafe creme, vin rouge, and cheese at every meal; although the coffee is pricier than the wine, which is of course délicieux, the coffee amazing every time, and of course, the cheese (sacre bleu! Mhwahahaha!)
DO start planning a return trip to Paris, or even better...MOVE to France!
