Jamie Glazov in his book United in Hate wrote:
laughter is discouraged - and is actually forbidden for women, and especially young girls. Nawal El Saadaw remembers that, growing up in Egypt, "If I laughed, I was expected to keep my voice so low that people could hardly hear me, or better, confine myself to smiling timidly. When Souad, the Palestinian survivor of an attempted honor killing, was flown to Switzerland, she was shocked to find females dressing as they wished, smiling and laughing without being punished and having people actually say "Thank you" to her - which had not happened once her entire life.
Jamie Glazov wrote how the late American Journalist Steven Vincent in his Iraq memoir noted that at one point he was sitting by the swimming pool at the Al Hamra hotel in Baghdad where Western journalists stay. He heard two American women laughing and a "chill" shot right through him. Their laughter made him realize that he had not heard a woman laugh in Iraq, "not in a free and unguarded manner, at any rate."
