My sister said Mary Elizabeth is suffering from low self-esteem, but I told her that she said the same thing about Sam back in November when she started dating Craig, and Sam is completely different. Everything can't be low self-esteem, can it? My sister tried to clarify things. She said that by introducing me to all these great things, Mary Elizabeth gained a "superior position" that she wouldn't need if she was confident about herself. She also said that people who try to control situations all the time are afraid that if they don't, nothing will work out the way they want.
