Sometimes you do something without thinking of the consequences. Maybe it's for a bit of fun, or to prove someone wrong. You don't really think about it at the time, or what could come of this bit of 'fun'.
You dont know what the future holds, especially when doing something as big as this. You can't just turn back and undo it. You can't fix some things, cause sometimes, it's just too late.
You can't back down, not when you've gone so far.
You have to keep going.
Right up until the very end.
