What is the difference?

Today in class, the difference between the mind and the brain was brought up. I find this to be very interesting because it seems like everyone had different ideas about what separated the two. That makes me wonder if there really is a difference between the two. Personally, I think the mind is more based on emotions and your subconscious feelings. The brain, on the other hand, deals more with physical things, and what is on the surface. For example, when you start to develop feelings for someone, thats usually not something you can control, it happens subconsciously in your mind. All feelings and emotions stem from your mind. Your brain deals with more mechanical things, like moving your arm or doing homework. I dont know how many people will agree with this theory, but this is just how i see it.
