A mother discover that her little boy is reaching his teen and knows its the best time to tell him that he should knock her bedroom door before going in..

says she,"I want you to knock on the door every other time you want to come in my bedroom-you might find me and your father in an awkward position or even without our clothes on"..

The boy replied," dont worry mother,before I come in I always peep through the key-whole before opening the door,and every time time I see you without clothes I always wait till I see that you've got dressed....like today I had to wait till dad stopped and you got dressed!!!"
