" A friend need not be kept either within sight or within reach. A friend must be allowed the freedom to find and follow his own path.
If one is fortunate, those paths will for a time join. But if the paths separate, it is comforting to know that a friend still graces the universe with his skills, and his viewpoint, and his presence.
For if one is remembered by a friend, one is never truly gone. "

― Timothy Zahn , Thrawn (Star Wars: Thrawn, #1)
