Because we have ALL made some of those, and sometimes it takes more than once to really learn it the hard way, whether they were little mistakes, or mistakes that affect your life forever. Mistakes ARE made to be learned from, and yeah, they might, and probably will cause self- loathing, but that's the price of being at fault.
And it's feelings like this, looking out the window where there are endless possibilities to the possible amount of water falling down from space. What is space? I haven't thought of that one in a long time. And I remember when I was younger, and I'd go to the near by pool and I can't remember how big the pool was but i'd tie my hair up, take a deep breathe, and dive across the pool, from one side to the other, without going up once. And sometimes i'd go under and close my eyes and imagine all the things impossible, because I was under water, and I was holding my breathe, and what rules exist then? And I specifically remember once on vacation, the pools had clear windows at the bottom, and i'd go under and talk to the creatures behind the glass, and i'd come back up and be in this world, once again.
