Sumthing

"Fool, you crazy or sumthing?"

just to clarify sumthing, i am not overwhelmingly good at math as u guys seem to be, so it may take me more time than u guys to understand sumthing …

… and sum-how that makes you feel good about yourself—as if you've accomplished sum-thing—as if you're worth sum-thing and not nothing.

… so that they can see if there might be sumthing wrong before they try to go thru the gate.
