Matt was a child prodigy, and child prodigies have it notoriously tough. He and I worked closely for a while. There is someone else important in my life that has somewhat close to mst's intellectual gifts, and similarly to mst they also have difficulty controlling their reaction to other people. However, unlike this other person in my life, mst did know how to express accountability and had been on a learning process to deal with his limitations. Matt and I never had beef, perhaps because we recognised that our respective strengths and weaknesses were complementary.
