    “You never gave up.  You never got discouraged.  If a roadblock appeared, you found a way around it.  You took a great load of my mind by not having to think of everything.  We’re a pretty good team together and I’m grateful for that.  I can’t tell you how much I appreciate your thoughtful analysis of issues dealing with the investigation and how it all ties together.  You clearly are a great PI!!”
