Blum has left many disappointed kids, without even an explanation for his departure. Everyone is still in shock how a teacher could just leave without an explanation or even a goodbye. Even though he was seen running at Lake Murray and is perfectly healthy. I think he should have at least said he was leaving. I do not think it was fair leaving his students behind, his Ta’s and grad students and those that he was supposed to give a recommendation letters to without a word. History 110 is not the same in lecture, I wish Blum would come back or let Linnea teach the course so it could go back to how it was before.
