a poem

Between square inches, the number of human vicissitudes; In time and space, ask carefully whether the summer of human beings is going to be cold; Be friends, the stars move, and the feelings remain unchanged; It's a bosom friend, and everyone remembers it.

The first two sentences describe how quickly time passes. The last two sentences describe bosom friends. No matter what happens, no matter where they are, their true feelings will always be remembered in their hearts, and there is also a sense of regret for the fleeting time. This is a poem praising friendship. It has gone through many things and time. It can stand the test of time and empathize with others, thus explaining the subtle difference between friends and confidants.
