A few months ago, my older daughter and I were arguing about something when my younger son came home from school. He told me that he saw our mother having sex with our neighbor's teenage daughter. My mom tried to justify that she told my husband's wife that they were only friends because they did not see them together. My daughter told me that it was entirely different. I asked my son why he said that, and he said that he saw them both having sex, and that my mom was screaming because she was so mad..
