Suppose one was working for a Professor. Then you mutually decide that it's not a good fit. The professor has been helpful in terms of suggestions for other people to work with and you found another professor who has given you some reading material earlier. How do I email the new professor if I can officially work with them? This professor is under the impression that I am working with the old professor, and I am wondering if it's relevant to mention that I am no longer? I have been doing the reading, but only started to more rigorously once I officially left the old group. I feel like I am thinking through this too much, but I don't want to write an email that seems negative in any ways since nothing has been negative so far. I am more worried about wordings. Thanks so much!
