"This is just a short note to let you know that after a 20-year friendship and about 10 years of working with you, it has been a pleasure. I don't think after all this time that we have ever had a falling out or dispute over anything we've ever done together. Not many people can say that. I know that you've worked hard to build your reputation to what it is today and I'm sure that it will keep you going for a long time to come, especially since your wife is by your side."
"Craig, as a businessman myself I'd be happy to work on any job you have. As a friend I'd do just about anything for you."
