Something for Nothing

I was already a little overheated and dehydrated when I headed out for an easy jog after work yesterday - it was very hot out and I'd biked home from work. As I rounded a corner on the hilly side streets of our lamely named NorKirk neighborhood, I came upon a group little girls who looked to be closing up some sort of lemonade stand. I was already preparing my valid "I don't have any money" excuse, when they called out and asked if I'd like a free drink. "Free?" I questioned. "Yes! We have--," "Do you have water?" I asked, interrupting their menu recitation. I stopped, and they handed me a bottle of ice cold spring water of their cooler. "Why are you giving away drinks for free?" I asked, surpised at both my good fortune and their generosity. "It's the end of the day," one of them answered, "we already made too much money." She pointed at the cigar box her friend held, which served as their cash register. Who knew there was such a thing?
