He said "Grandma what is it called when two people sleep on top of each other?" Being a progressive Grandparent, she thinks I might as well tell Johnie the truth. Grandma says "Johnie that's called sexual intercourse."Johmie goes outside to play. About an hour goes by and he is back in the house with a long face. Grandma says "What's the matter Johnie?
