Tom , you promised to cut the lung . You won't forget , will you ?   No , I assure you .   And you'll repair the television , won't you ?   Ok .   Do you promise ?   Of course .   And Tom , you will help Johnny with his homework , won't you ?   I'll see . I will if I can but I won't promise .   But you'll promise not to be late for dinner tonight , won't you ?
