PROBLEM: Person1: Let's have seafood tonight and then go see the new movie at Mall Cinema.Betsy told me it's a beautiful love story and I shouldn't miss it .
Person2:Oh , Goodness , please not again.That ' s what we did last week .
Person1: No , we didn't . Last week we went to see that movie about a man's struggle against mental illness .
Person2:Right , it was a chick flick , just like this one , so what's the difference ? Besides , this is the last week for the third movie in Destroyer series and I want to see that on a big screen . Action movies need to be seen in a theater on a big screen .
Person1: Oh , yeah , and I did promise to see it with you if we went to that movie last week.But you liked that movie , didn't you ?
Person2:Oh , sure , it was great . I had popcorn for dinner and paid the price of a movie ticket to get a two-hour nap .
Person1: It wasn't that bad , and you're the one that insisted on skipping dinner.We went to an excellent restaurant .
Person2:That place doesn't have a single meat dish.Just fish and shellfish and you know I don't like fish that much .
Person1: And I don't like meat that much.The only meat I eat is chicken .
Person2:But when I pick the restaurant , we go to a place that has both chicken and fish . I always respect your food preferences .
Person1: Well , I suppose that , to be fair , you should get to pick the movie and we can go to a restaurant that serves meat .
Person2:Now you're talking , we can see that love story next time .
