Dear David, 

We only met in person twice and both of those were over a glass.  You were tremendous company and left me wanting to get to know you better; I deeply regret that will not happen now.  In the short time we worked together I quickly learned to trust your judgement and valued your insight and pragmatism, most importantly I had a sense of really lovely person who brought positivity and a smile with him. 

You will leave an enormous hole and listening to others who knew you better it is obvious that you leave a lot of love behind. 

Richard
