Say to him, "I was thinking today about all of the things about you that I respect, & I want you to know that I really respect you." Exit the room. When he asks, if he asks, be prepared to give him at least three things.
1. I respect his hard world and willingness to get up and continue to work even though it may not be the best situation.
2. I respect the way that you are my biggest team mate and how hard you work to help me out.
3. I respect you for communicating with me no matter what the issue may be.
