Jack Wiwcharyk is bugging his mom about something he heard on the radio. The first-grader says his parents listen to a lot of public radio."Talk, talk, talk," Jack says during a phone conversation with him and mom Niki Walker from their home near Toronto in Canada. "I don't understand all of it."What he didn't understand were reports that the United States and other countries may attack Syria, a country in the Middle East, because they think Syria used poison gas on civilians, including children. Other countries and many Americans are against an attack, and the arguments fly back and forth on the radio, in newspapers and maybe in your house, too.
