“friend is someone you can trust and admits you whatever you are”

“There's ways you can trust an enemy you can't always trust a friend. An enemy's never going to betray your trust.”

“You have to trust someone before you can have rituals with them.”

“It is important to have questionable friends you can trust unconditionally.”

“...maybe, if you're lucky enough to have someone who really cares about you, someone you can trust, someone who reminds you to believe in yourself, you can survive absolutely anything...”

“It is true, of course, that there is no way of knowing for sure whether or not you can trust someone, for the simple reason that circumstances change all of the time. You might know someone for several years, for instance, and trust him completely as your friend, but circumstances could change and he could become very hungry, and before you knew it you could be boiling in a soup pot, because there is no way of knowing for sure.”
