Person1: Are you still coming to my place for dinner tomorrow night ?
Person2: Of course . Is the dinner still on ?
Person1: Yes , I was just wondering how you and your roommate were planning on coming to my place .
Person2: We were planning on walking both ways since the weather is still nice .
Person1: That's what I thought you would do . Listen , I live in a bit of a rough neighborhood . It's just down the street from all the bars . You probably don't want to be walking around after dark .
Person2: It can't be that bad .
Person1: I wish it wasn't , but there is actually a lot of crime and prostitution around here .
Person2: Really ? I never would have guessed . The criminals must only come out in the evenings , because I've never noticed anything strange when I've been at your house in the daytime .
Person1: Do me a favor , and take a taxi . It'd make me feel a lot better .
Person2: Ok , we will . How do you get around in the evenings ?
Person1: When I first moved in , I walked everywhere . But within a week , I had my purse stolen just a block away from the police station ! Now , I always take public transportation .
Person2: Has anything else happened to you ?
Person1: Nothing else has happened to me , but I have seen quite a few fights on the streets after the bars close .
Person2: Well , we'll be careful . Thanks for letting me know .

Person1: Why ? If I eat less , then my body will start eating away at my fat reserves , right ?

Person1: So you are saying that I should eat , but I should just watch what I eat ?
Person2: Yes ! You can also try to reduce your intake of carbohydrates and foods that are high in cholesterol . You can have steamed veggies or increase your protein intake found in chicken or fish .
Person1: If I do all this do you think I can lose twenty pounds in four weeks ?
Person2: Don ' t count on it .
