We live in the country & have our own water well. It's great water. A little, teensy bit on the hard side, but it tastes great. Being the lazy American consumers that we are, however, we buy bottled water. Cheap bottled water at Wal-Mart. It's just too darn handy to have it ready to go, grab a bottle and take it with you, grab one out of the 'fridge. Especially handy for sporting events. Nice to have outside when you're working so you can put the cap back on it & get no bugs in your water. Which is also a nice feature for drinking anywhere in the house (with kids). And it's handy to offer to visitors, too, especially those picky ones that don't care for well water (like my step-mother-in-law, who won't even use ice cubes at our house if they're made with our well water... she always asks, "are those cubes from your well water?"... with the words well water here accompanied by a facial expression including a wrinkled up nose, like well water = dog turds).
Kevin and Sammy have found a use for the white plastic water bottle caps. They throw them at each other, preferably while the other one is not expecting it. Rarely scoring a direct hit. (Try to throw one, you'll see what I mean... those bottle caps don't always go where you think you're throwing them.) Some of these battles get pretty feisty and loud. We've dubbed it the year of the bottle cap war.
