I’m writing this from my home base in Bentonville, Arkansas, savoring a few luxuries I’ll never again take for granted after four weeks abroad—namely, air conditioning, ice, and Diet Coke. But with that, it's definitely a tradeoff. I can’t help but miss my pistachio gelato from Pasticceria San Gaetano Da Mariano, my daily cappuccinos, and being just a walk away from authentic Italian pizza.
