I recall one instance when one of them was transiting through Singapore and requested a call on the President that very morning. We hurriedly put up the request, expecting the President to decline. To my surprise, he agreed, even though he was not at the Istana that morning -- he had to rush down for the meeting. As far as I remember, never once did he decline a call. Such was the nature of the man. He took his responsibilities very seriously, and carried our flag with much grace and dignity.
