Still no response from my major professor. I have been alone in the lab since Friday afternoon. All of my labmates are out of town. They will be back tomorrow. I have a level of confidence after sending that letter yesterday and I am curious as to how the major professor will respond. Since my professor is one for calling us down individually to his office to "talk", I have decided that I will be requesting a written response to my letter. There are clarifications that I want to document in order to better protect myself and my future.
