Context: I ' m impressed we managed to stick to the path . It was all worth it though - we got to the top of the mountain at about 6 am and watched the sunrise , which was really spectacular . It was also absolutely flipping freezing and I had n't brought enough layers . That was n't pleasant .

Answer:

I was not prepared and forgot how cold it could be at 6 am



Why did n't I bring enough layers with me to climb the mountain ?
