The song "time is running out" sounded again in the rehearsal room. The title of this song also appropriately describes the current mood of this group of young people. In three months, my four-year college career will be over. Four years is not a long time, at least for this group of young people, four years goes by too fast. They haven't played enough music, gone on crazy enough trips, or fallen in love enough. They will all be baptized by society in three months. Time passes, and all that remains of youth are memories.
