I am finding the following moral problem, and possibly people with more experience could help me.
One of my Master students (who recently finished his master studies) is applying for PhD positions. Despite my good scientific opinion about him (and his master thesis research), my personal opinion is starting to change. He is a good student, but not an exceptional student. This means that he can of course prepare a good PhD. The problem comes when I start suggesting places he could apply (and you know, getting PhD funding is not straightforward), he has many obstructions: things like 'I do not like this country', 'in this country phd's are of 3 years and with teaching', 'The subject of this phd is the same area of my master, but not directly related', and things like these.
I am happy to help, but this is becoming tiring. As a master thesis advisor I am the one who is expected to write the recommendation letter. After having these encounters I do not feel I should write a very positive letter.
How should I manage this situation?
