"OK, let's discuss the possibility of your having a research assistant.  We are prepared to offer you a paid graduate research assistant (minimum wage; sorry, the wage level is not negotiable) for one calendar year. Is this acceptable?"

Your response: 

1. "Yes.  That will be fine.  Thank you!"

2. "I'm sorry but you'll have to do better than that!"

3. "I was really thinking of having the funding for a 'longer-period'...Say, three years."
