I received a surprising e-mail from a previous boss asking if we could collaborate in a small project. It appears that she would expect me to plan it. We have done similar things before, and the projects were all right. However, she was also quite mean to me at times. I ask for wisdom in this. I have an idea but I wonder if I should share it with her. I do not even know if my current job contract will be continued next year. In theory, this invitation is an honour.
