Every time he called I used to respond, “William Samoei arap Ruto, how are you.” Then of course he became deputy president and suddenly the friendly familiarity became inappropriate. When Uhuru called it was easy to say, “Hi Boss.” When he calls now you suddenly find yourself standing at attention, irrespective of where you are, saying “Your Excellency Sir!” As President Harry Truman said, “the office makes the man”. Others may argue that the man can also diminish the office, but I beg to differ.
Donald Trump with all his absurdities and eccentricity could not damage the presidency of the US. One week after he left office, he became a non-entity. Such is the power of such offices. Our presidency may not have a 245-year history, but we have to keep history in mind before we act in haste to start impeachment processes.
