The Young Kids of Today

These young kids of today, sometimes I really don't get them, and it's then i feel old old.
Like for instance today at work. The NRL footy game at Telstra Stadium, I was sitting in my Box Office waiting for customers... when a bunch of young kids around say fifteen walk by the window. They stop out the front and talk about something, I look at what one of these kids are wearing, hes got a backwards cap on, a singlet, grey undies, and denim three-quarter pants. How did I know what kind of undies he had on, well his pants started around the bottom of his arse. Thats way too much undie show for anyone liking!
So to make matters worse, this kid I was staring at trying to figure out what kind of mother would allow her son to step out of his bedroom, little lone go out of the house to a football match, he comes up to my window.

"I wanna change this" he says to me waving his ticket in my window
"There are no exchanges" I say to him, as this is policy
"No, I want to change it" he says to me again
I sit there wondering if I was talking to myself
"You can't change it" I said, trying to bring myself down to the new generation lingo... which seems to have lost all common sense.
He gummbled and then walked off.

I am hoping to god that it was just that one kid who doesnt understand that when you want to change something you have already bought for something else from the place you bought it, it indeed is called an EXCHANGE.
Is it me, or is it hard to understand what an exchange is... I swear I even knew that at 15!
