Thanks last-Samorai, sjo4 and daledale!
Las-Sam, I forgot to say that it is the same with us! She is far ahead of me in the PhD and has loads to do, but can not let me see do anything in my own! any experiment, she has to be in it! she says she wants to learn! but the problem is that she would not let me do it (she does not want to be an observer she wants to do it)! which is fine, but then when she has her private meetings with the sup she reports that she has done the work (MY work! and I have been lazy!)! I know you would say talk to the sup to have separate paths! I did ! The sup says ok, from now you will do separate experiments, but when we have joint meetings it is like I have not talked to the Sup! The sup would be like: Yeah, I guess we can do this one joint too!!!!!
