The time has come to say goodbye .   So soon . It seems as if you just got here .   I feel that way , too . But all good things must come to an end , as they say .   It certainly has been a pleasure seeing you again and renewing old memories .   I've had a great time and thank you for your spending so much time showing me around .   It was fun for me , too . It gave me a chance to get away from my routine .   You'll be out to see me next year , as you promised ?
