The nun was teaching social studies to a class of young girls. As their weekend homework, she told the girls to do a good deed and report back on Monday.On Monday morning, the first girl reported that she had bought food for a homeless person. A second girl was proud that she had seen someone drop a twenty dollar bill, and she had returned it to its owner… Another girl had spent a few hours reading to a blind person…A group of four girls said they had helped an old lady cross the street…The teacher stopped them at that point. Thats very nice, said the teacher, but why did it take four of you?Well, said one of the four, she didnt seem to want to cross the road too badly.
