There is 3 ways you can abide by, mate. The first one, you honestly don´t want to get any close to: Living happy ignoring the surrounding, unstoppable terror is just not an option. No. But the other two. The other two, for people like you and me, come up as the only 2 possibilities. You can either be a fucking bloody grump for every single day of your life and express yourself as a being in constant despair, or you could just be aware of the horror that exists around you and still fucking have it with a massive smile on your face.
Living in anger is for complete fools, my dear.
