OK this requires class participation. Here's how this works you get to ask me yes or no questions to recreate a scenario. As you unveil certain aspects things will get alot clearer. I'll giv an example... A guy is on an elevator the power goes off and a few minutes later the power comes back on and the man sobs "My mothers dead". How did he know?
Questions you might ask...
Is his mother there? No
Can he see his mom? No
Is he in a hospital? Yes
Was his mom on life support? Yes
Answer is his mom was on life support power went off life support stopped. Alright if you like it play if you don't don't we'll just see how this goes.

A man lives on the 20th floor. Everyday he goes to the elevator and goes from the 20th floor to the 1st floor. Everyday he comes home and goes from the 1st floor to the 15th floor and walks the last 5 flights of stairs to his apartment. Why?
