Dear SARA BROWN,
Everyone knows how much you did to keep my clients happy during my unscheduled absence from the office. I was initially worried about work when I found myself laid up after that car accident, but as soon as I knew that you had agreed to cover for me I knew that my clients were in safe hands. I have heard excellent things from all of my clients and am grateful for the effort you put in.
