Life changes. You get it all lined up just the way you like it & then something beyond your control comes along & bumps you off center. How nice it would be if you could get everything just the way you want it & say, 'Okay, now, stay.' But nothing stays the same. You grow up, make friends, lose friends, go to college, lose track of people, meet new ones, & sometimes you ask yourself why. But all I can tell you is the every single experience you go through like this changed you in some way. Every new person who comes into your life changes you. Every moral dilemma or emotional experience you come up against changes you. It's your job you decide how. That's how character is developed.
A nurse once told me that wounds will not heal if you urgently put band aid on it. Sometimes you just have to let it bleed, give it some space for healing & when you think your wounds are already cleansed, that's the time you can use a band aid for it. Remember: the more you cover yourself from pain, the more infected you are.
now I understand the meaning she literally meant.
