Friendship is a feeling of comfort and emotional safety with a person. It is when you do not have to weigh your thoughts and measure words. It is when someone knows you better than yourself and assures to be by your side in every emotional crisis.

Friendship is a relationship with someone who loves you in spite of yourself.  A friend is someone who has broad shoulders to lean on, ears that listen and a mouth that doesn't repeat what those ears hear.   A friend  passes no judgment upon you. A friend can speak his/her mind without "walking on eggshells" for fear of hurting your feelings, because a friend would never do that in the first place.  A friend is someone you can trust to always tell you the truth. 
 

Friendship is beeing able to accept each other as you are, beeing able to tell your deepest secrets to and beeing there  for each other in bad times, not just in good times.

Love, trust, affection, accepting being there for each other and compatibility.

Friendships are hard to find, difficult to leave, and impossible to forget.

  friendship is been able to say I am sorry and truly mean it

Friendship is you not being my enemy.
