Stupy, I wasted yesterday on you, I'm not wasting today on someone who doesn't understand sets and those subsets that are elements of larger sets. Go back to 7th grade, if they're not teaching that stuff even earlier now.  I can't imagine how you ever got through Algebra 1, week 1, though maybe my small, rural high-school had better math teachers than your urban one did.  You've always been a very young 12, going on 2.  It's hilarious in someone six times that. 

Update:  Stupy, your best friend won't tell you but you're a schmuck.    And that's what your best friend thinks of you, too.
