"Sometimes the only way to help someone, is to walk away."
As hard as it is to admit, it's true. It really sux when it happens to you, but sometimes you have to bear it and move on.
I chose that as my quote to represent you Itachi-sama. I think it describes what you had to do very well, which in turn helped to make you who you are. Also credit goes to me for it, since I added it myself.
