ME:  I really like this theory.  JKR introduces us to magic via 
Harry's emotions (the glass on snake cage on Dudley's B-day).  
Hagrid even asks him if he has ever made things happen when he was 
angry or sad.  The Patronus and Avada Kedavra we are told have 
emotional links.

This could be very important latter...as we are told that Harry is 
protected by Lilly's love.

I want to add a question here.  What is "the old magic" Lilly 
supposedly uses?  Maybe this has been discussed prior, but I have 
heard one theory (jake...who I hope posts his theory), but am 
interested in others.
