 As we arrived in a solemn procession the students pelted us with toilet rolls . They kept hold of one end , like streamers at a ball , and threw the other end . The Queen Mother stopped and picked these up as though somebody had misplaced them . [ Returning them to the students she said , ] ' Was this yours ? Oh , could you take it ? ' And it was her sang @-@ froid and her absolute refusal to be shocked by this , which immediately silenced all the students . She knows instinctively what to do on those occasions . She doesn 't rise to being heckled at all ; she just pretends it must be an oversight on the part of the people doing it . The way she reacted not only showed her presence of mind , but was so charming and so disarming , even to the most rabid element , that she brought peace to troubled waters .
