The Urban Dictionary defines a friend as:
A friend is a partner, not a leader or a follower.
A friend is someone you love and who loves you, someone you respect and who respects you, someone whom you trust and who trusts you. A friend is honest and makes you want to be honest, too. A friend is loyal.
A friend is someone who is happy to spend time with you... Someone who forgives you no matter what you do, and someone who tries to help you even when they don't know how. A friend is someone who tells you if you're being stupid, but who doesn't make you feel stupid.
A friend is someone who would sacrifice their life and happiness for you. You don't even think about who's talking or who's listening in a conversation with a friend.
A friend is someone for whom you're willing to change your opinions. A friend is someone you look forward to seeing and who looks forward to seeing you: someone you like so much, it doesn't matter if you share interests or traits. A friend is someone you like so much, you start to like the things they like.
The word "friend" comes from Old English "frēond", which is actually the present participle of "frēogan", which means "to love" and "to honor".
I agree 100 percent. You are either all in or all out when it comes to friendship. Anything else is not truly friendship, correct? What are your thoughts?
