Back at the "Wellness Center"

Sitting down, and passing Billy a root-beer, Grrr popped a can for himself and said " Rex boys in the yard busting your tail again?"A shocked Billy almost choked on his root-beer.
As he found his breath, Billy 

looked at Grrr and said "Yes, they....how..how..did you ...know???
"Hey, Kid I was in JH once myself you know".Replied Grrr with a smile.
"But ...but, said Billy YOU are Grrr Rex!"
"Yeah, now. At 13, I was Grrry and there were a LOT of bigger rexs around who figured steppin on my tail was funny"

Mr. Grrrr. I..I..like music and that stuff but the boys call me names my mom and Mrs. Bronto told me to walk away or tell the teacher...but.."

"I know..being called a "rat" and having no friends is worse. replied Grrr.
"Yes. look at my claws, mom makes me clip them and even if she didn't I ...I don't know how to fight...I...I am not afraid of being hit..but if you look stupid ..they say I fight like a girl, everyone laughs

"I am starting to hate school and ...I ..hate being weak and it is so unfair."Billy said.

"Boohoo kid" said Grrr, "Poor pitiful you".

Billy's head came up with a roar.

Smiling, Grrr said, "That is more like it son, we are rex .
We roar at life not cry about it." 

Billy. "I know that is true Mr. Grrr and I want to roar but the boys.."
"Listen son, I am going to sign you up in my son's Dino-karate class, it will be a lot of very hard work Sensi Godzilla is a very serious dino. But if you do the work, NO ONE is EVER going to step on your tail for fun again.  It will take about a year for you to get good and .." Grrr said..  

"A year!!!   But Mr. Grrr what..I mean a year?"
"Not at problem kid, said Grrr, tossing Billy a button. Wear that on your coat."..the button read:

I AM A FRIEND OF GRRR REX...YOU GOT A PROBLEM WITH THAT?

"Sensi Godzilla will tell you when it is time to return it to me." said Grrr.

"Ahh..Mr. Grrr. We...we don't have a lot of money, since the volcano got popa. Mom works but."
"Kid, said Grrr, I see from your file that you have been taking piano for 8 years? "
"Yes, Mom is a piano teacher  but.."
"Son, eight years is a long time, you any good?" 

 Mr. Grrr, I played two professional shows..I", said Billy with pride, "am very good."
"So you should be able to teach a kid just starting?" Asked Grrr.
"Sure, I offered to teach the kids at school ...but.." said Billy.
"Excuse me kid, I have to make a phone call." Grrr stepped out of his office and returned several minutes later.
"Well, kid, Sensi Godzilla, wants his son to learn piano. You teach his son and in exchange Sensi Godzilla will teach you. deal?"
"Yes, oh, yes DEAL" said a overjoyed Billy. "I won't let your down Mr. Grrrr."
