Get the pitcher.

Setting out this pretty-as-a-pitcher with ice water when friends stop by is such a nice, hostess-y touch (rather than filling at the tap glass by glass). Guests can refill on their own as they need, and you can put your feet up, too. When the guests are a little less unexpected, fill it with a gingery sangria or a batch of watermelon palomas, or pack it with sunflowers.
