What do you mean by punctuality?

This sentence is more or less a negative evaluation of youth.

Good things come and go in a hurry. It is said that youth is a sad thing, and we can know that it is perishable with fleeting time.

Time flies can only be synonymous with the traces left by the past years, and youth refers to the most brilliant and dynamic description process in life. The so-called fleeting time to get one's hands on youth refers to a low-key performance, or there is irreparable pain in that memory, or there are many happy things worth remembering in the warm time, which is not entirely ironic. There is a strange saying, a spring breeze and a dream, and the past.

Of course, this is not derogatory. The notes of youth are engraved on the time board of years.
