I chose the PI as answer to one of them, something to do with PI is not above 1. It was choice A for me and I think I am right on that one.
Anyway, I had some really nice dinner and went to see some penguins play. Then on my way to a pub, I dozed off in the car at about 9:30 pm. So my friends drove me home and we had some nice wine. I found it REALLY difficult to stay awake after 11 pm, which is very weird, because I sleep at 3 am almost everyday.
