Content introduction:

Eighteen years is too short for life. 18 years is too long for youth. However, when life is only a short 18 years from the beginning, this feeling seems to have gone to death from the beginning, and it is too late to see the scenery along the way, and the journey of life has ended. However, even so, she still said: life is the countdown to death from the beginning. The difference is that I only have a little time left, and you continue to count down. Slowly recall the lost time, there may be a lot of things left in the cracks of memory. Everyone regards his life as a grain of sand with only eighteen years. The more time goes by, the more precious things we accumulate. Don't give up something easily. You don't cherish it because you don't understand it now. In April, all the flowers in the world are out, but I just want to tell you sadly that there are not many grains of sand in my life.
