One day a mother took her 6-year-old son with her to visit a friend at work. Everyone there knew her, and she was offered a cup of coffee. That day, as one of the employees went to make more coffee, her son followed her and asked, "What are you doing?"
"I'm making your mom's favorite drink," she answered.
Imagine the woman's shock when she heard her son say, "Wow! You know how to make beer?"
