"They say that sometimes you have to build up your mind's shields to see who will break them down. But what happens if you build them too high?"
"Probably what's happened to me; you get left in solitude. It becomes too hard on those closest to you, it ruins lives. Worst thing is, yours is probably the one that was least affected. The one you thought would always be there for you is the one affected the most, the one ruined the most."
"And after that?"
"Some people never are the same, actually, no one is. And sometimes the one to finally break your mind's shields is your worst enemy."
