A coming-of-age ceremony

I become 20 years old soon. I attend at the coming-of-age ceremony of the next year. In late years it has various problems. The problem is the badness of the manner of the youth.They whisper and interfere with the ceremony.I think it to be sad.Feeling nostalgic for that we meet the friend after a long absence.However, I think that I should follow the manner because we are not children anymore.
