When people reach middle age, they should learn to do subtraction for themselves.
Put aside unrealistic wishes, the past that can't be turned back, people who don't need to care, and only a few real confidants are enough.
As Wang Guozhen wrote in the poem "It's good to know you":
One day, we really met, and we were too happy to speak. We just laughed and said, it's good to know you.
Life is long, so don't be afraid to walk alone. One day, you will meet several people, exchange the hottest sincerity with your most sincere soul, and go forward with each other.
