I have a male friend since senior high school until now
Friends who always have good likes and sorrows

We were so close that other friends even thought we were dating, how we did not go around often, eating in the school cafeteria, studying together and sitting on the school inscription enjoying the evening at dusk

By the end of school, we often fight. Even when our school breakup did not greet each other. It felt awkward at the time. But, that's why we understand each other what that friendship really means. Friends who are always in likes and sorrow, friends who love each other, remember each other, jealousy when one is close to another friend.
Friends who without hesitation to rebuke when wrong, always helping in times of trouble, sharing happily.

Strange indeed, affection as to brother but not brother. Such affection to the girlfriend but not in a courtship relationship. And surely a compassion that exceeds compassion to friends in general.
