The contract banned "inappropriate or disruptive behavior," from
parents and students, including screaming, howling, hooting, dancing,
non-traditional handshaking and others.

they might as well just send their students the diplomas in the mail then - what's the point of inviting family members and friends if no emotions (pride/happiness/...) are to be expressed?!

Dumb!

Ah, "non-traditional handshaking" as inappropriate behavior. I see.

Oh, the horror of it.

I wonder if it will go on their pemanent record?!!
