"Awesome"

I asked Boy how school was today and he replied, "awesome."  I was surprised by this because normally he says he doesn't know or that it was boring.  Interested, I asked him why his day went so well.  He fumbled over his words for a few minutes not managing to say anything coherent.  He stopped for awhile seeming to be thinking about what he wanted to say.  

Then, with a big grin, he excitedly spat out, "The teacher had a see through shirt on today." 

Awesome.
