Hi , Sara , what are you reading ?   Hi , John , I am trying to find a carpenter .   Why ?   Well , I want to build a deck in my back yard .   What for ?   So I can have a special place to hang out with friends , and also do some barbecuing on weekends .   That sounds cool . Do you mind if I recommend myself for the job ?   You ? Do you have a carpenter's license ?   Yes , of course . But I only freelance on weekends with my uncle .   Wow ! That's cool . So , let me give you some details about the deck I want .   Please go ahead , I am listening .   I'd like my deck to be at the same level as the back door .   Is your back door higher than the ground level ?   Yes , the back door is about four or five steps higher than the ground .
