Dear Andrew Hall,
Sarah, well done on reaching a greatly deserved retirement. You have always been one of most loyal employees, and I cannot express how much you are going to be missed. The fact that you were always willing to help out with what ever work needed doing made you a pleasure to work with. With you gone our office will certainly not feel as bright as it did. What ever happens make sure you stay in touch.
Sincerely,
Botond
