Life is when you look down the drain at N+2 years of age at the bathroom of your girlfriend's flatshare (which is a fragile bathroom of a 4-girl flatshare I remind you), and think "I never thought I would even end up in this X city of this Y country of the world, and have a girlfriend of a completely 'opposite' but yet so affiliated culture when I was only N years of age"...

So, the calculation is:

2 years down the road, and you end up in a completely random sewereage entrance point that you didn't imagine of, and you're happy with your 0.5 alcohol concentration in the blood and the friends in the 5 m2 British kitchen modern design 2m. away from where you are, having a happy conversation surrounded by architecture put initially up for an Southeastern Asian household.

In essence... It's all about beauty of life.
