what defines a true friend? 一个人需要多努力才能成为对方最要好的朋友？过后还需要多努力才能维持这种关系？

After the event, we were planning to go out for lunch. and i thought we were going. together. something cropped up. 你有些不耐烦吧？so obviously i couldn't leave you alone and went along with you. frankly speaking, i was expecting them to hold you back or at least followed along and went to lunch together. but that didn't happen. 真的以为你们是很好的朋友，对方心情不好以为你会陪她。我错了。口口声声说的“依靠”，just disappeared so quickly。reality. 这就是人类。而且当中部只是一个。有两位。没有一截叫住他，没有一个陪着他。Is this true friendship? 或许是我自己吧事情搞大。but it's the truth isn't it? 所谓的友情，won't you understand if your friend's feeling a little down and needs your company? 眼前的这一切我看得很清楚，很彻底。原来真正的友情，有那么难找。
