Sitting underneath the Godswood all day, not being able to leave in fear of falling prey to the white walkers, can get incredibly draining, even if you aren't doing anything. Especially when you can only sit there and talk to Meera while Hodor curls up in a corner and tries to keep warm and while Bran has visions.

You feel just as useless as Meera does, but you can't do much about that. Meera is busy grieving her brother's death, even if it was for Bran's sake. Hodor was fun to talk to, but it starts to get boring when all he can say in response is "Hodor", and it's not all worth talking to Bran. He has to focus on his visions.

So you sat on one of the large roots and huddled up in your fur cloak, trying hard not to freeze to death.
