When I heard the burble of a stream, I picked my way through a patch of bramble to get to it. Hayley was right behind me, fighting through the branches instead of ducking them. Sam got poked in the eye. When she cursed, Hayley jumped and slipped on a muddy patch. Corey ripped his shirt on thorns helping her up. All three complained, loudly and bitterly.
"We need more water," Daniel said. "Which means you need to get to it, because we can't bring it back for you."
"Well, maybe if Hayley was more careful," Sam said. "Not letting the branches fling back."
"Well, maybe if you weren't walking right behind me," Hayley said. "Why do we need water anyway? We drank before we set out."
"We need to drink from every stream I can find," I said. "As I've said, dehydration is the biggest risk we face out here."
"Okay," Corey said. "But could you find a path without mud and thorns?"
"I'll make sure the next one's paved."
Daniel leaned toward me as we walked. "I bet if we bolted, we could lose them in ten seconds."
"Don't tempt me," I muttered. He grinned and put out his hand to help me over a muddy patch. I crossed, then called back a warning to the others. Daniel seconded the warning and pointed out the mud. Hayley still slid and fell.
