That night, the tent that I had been alone in for so long was suddenly heaving with bodies, and piles of rope and kit--with Neil, Geoffrey, and Graham squeezed in beside me. I tried to drink as much boiled water as I could get down. I knew that I would need to be as hydrated as I could possibly be to tackle what lay ahead. So I drank and I peed. But still my pee was dark brown. It was almost impossible to hydrate at this altitude. The ritual of peeing into a water bottle had become second nature to us all, even in the dark, and even with someone's head inches away from the bottle. We each had two bottles: one for pee, one for water. It was worth having a good system to remember which was which. At 10:00 P.M. I needed to pee--again. I grabbed my bottle, crouched over and filled it. I screwed it shut--or so I thought--then settled back into my bag to try and find some elusive sleep. Soon I felt the dampness creeping through my clothes. I swore to myself as I scrambled to the crouch position again. I looked down. The cap was hanging loosely off the pee bottle. Dark, stinking brown pee had soaked through all my clothes and sleeping bag. I obviously hadn't done it up properly. Brute of a mistake. Maybe an omen for what lay ahead. On that note I fell asleep.
