A Quote from Portal 2
Cave Johnson
All right, I've been thinking, when life gives you lemons, don't make lemonade! Make life take the lemons back! Get Mad! I don't want your damn lemons! What am I supposed to do with these? Demand to see life's manager! Make life rue the day it thought it could give Cave Johnson lemons! Do you know who I am? I'm the man whose gonna burn your house down - with the lemons! I'm gonna get my engineers to invent a combustible lemon that'll burn your house down!

So you know what? You win. Just go.
