What's Your Name?

Four boys are huddled together spraying silly string at each other. Much of it is ending up on the floor.
"Hey guys, come here please."
"Why?"
"Um, really? You need that explained?"
Three of the boys take off running, which makes me laugh. These bad-asses are such thugs that they run from a 5'8" teacher asking them to come talk about the situation.
The fourth boy turns and walks away.
"What's your name?"
"Why do you care?"
"Because you and your crew just made a mess in our hallways. That's not a good choice."
He keeps walking; so do I.
"Well, what's your name?"
He ignores me.
"Where are you headed?"
He ignores me.
This isn't the first time one of these wannabe tough guys refused to give up their name. They're willing to just keep walking and ignoring us until we come across security (which doesn't happen regularly) or they realize many of us just don't have the will to keep following them--something I am willing to do.
Just another day in paradise.
