friends

this is it, true meaning of friends (for me maybe). they feel happier and they forget everything that make them start to happy before. till the gloomy day came back to them, they will see and start to realize which human being is suited to them, and can make them happy back. at the same time those human being that they need most will say "don't be upset, i'll always be with you". this is what what they call 'friends'.
