Question

at the base of the mountain were three signs. one showed a stick figure falling off a cliff. another showed a rock hitting a stick figure. a third said simply, no emergency services. i turned to maria and asked her whether she really thought this was a good idea. are you trying to say im not tough enough? she asked. actually, im saying maybe im not tough enough. maria laughed and started up the rocky trail. i followed her and told myself that the warning signs werent meant for us. they were for people who had no common sense. within half a minute, i was panting like a dog. two guys passed us, their faces sunburned and smudged with dirt. good luck, they told us. they didnt smile. after that, i started to notice that the other hikers had more gear than maria and i did. they also had huge, bulging calf muscles. half of them looked like olympic athletes. how much water did you bring? i asked maria. about half a liter, maria said. why? we should have brought more, i said. at the first mile marker, we downed half of the water. the sun beat down from a cloudless sky. i looked up the steep path, strewn with rocks and gravel. my legs were already trembling. what a great view, maria said. maybe this is a good stopping point for us? i am so glad to hear you say that, i told her. cmon, ill race you to the bottom, she said, heading down the trail. i followed her, taking my time on the steep parts. this was a race i had no intention of winning.
