Friendship is often compared to a flower, full of fragrance. When the light was bright, it is easy to wither away. Friendship is often compared to a tree. It will last forever, blocking the wind and rain, but it will be destroyed by the sparks. True friendship, from the front and back, should be the same. It is impossible to see a rose from the front and a thorn from the back. Wisdom, friendship, this is the only light to illuminate our night.You need more skills to maintain this kind of beautiful and fragile emotion. Friendship is as pure as the fog in the morning, and it can only be consolidated by loyalty. Only by keeping a certain distance between friends can friendship last long.
