I'm not quite sure what you mean by "if @asleep = false". Anyway, you 
cannot leave out the if statement. You cannot even put the 
"passageOfTime" and the "puts" into a single if statement, because the 
"passageOfTime" may change the value of @asleep.

The dragon may wake up during passageOfTime (when he's hungry or poopy). 
So after passageOfTime you have to check again if he's still asleep.
