I recently asked someone who observed my teaching to write me a letter of recommendation. She replied enthusiastically that she would be happy to help but was pressed for time. She asked me to write the letter and then send it to her so she could make edits.
I'm confused by this since I've received 7 or so other letters over the years speaking to my strengths in research. Is it acceptable to write the letter on behalf of the person you're asking for a letter from? If so, how do you even go about the task of writing such a thing? I'm a bit too... shy to ask her if there was some misunderstanding, so I'm asking here first.
