Is arresting those who cannot follow the rules the answer? I have been to several graduations lately - a couple of college ones, three high school ones. They are not like my own graduations.
People feel compelled to yell. Great. It probably makes your own child feel good but it makes it difficult to hear the next names.
Once their own graduate has graduated, people are incredible. They take phone calls and hold conversations. Loud conversations.
They talk amongst themselves.
They let their children (and I mean anyone under the age of 18) run amok.
They treat it like a football game.
Or the movie theater.
I think people no longer consider where they are or what is happening around them.
