Input:  Person1:       your daughter will be back soon . I'm going to start making dinner . You can just watch some TV in TV room if you like . We just bought a new TV with a LCD screen . The remote control is on the coffee ta  
 Person2:would you mind if I helped out in the kitchen instead ? I do enjoy cooking .  
 Person1:        this is supposed to be your vacation ; we'd like you to just relax .  
 Person2:cooking makes me feel relaxed . So , what are we cooking ?  
 Person1:        ok , well , we're going to make a pan of lasagne , a salad , and some garlic bread . Here's the recipe . Do you want to get the ingredients we need out of the cupboard ?  
 Person2:sure . We should probably pre-heat the oven right away , too .  
 Person1:        that's a good idea . Can you set the oven to 200 degrees Celsius ?  
 Person2:that's a bit high for lasagne . I'll just set it at 180 degree and we can take it from there .  
 Person1:        fine . I'll just get out the casserole dish , the saucepan , the salad bowl , and the baking sheet .  
 Person2:you know , I could do this myself . Why don't you go get the screwdriver and the pliers and go fix the vacuum cleaner so it works better ?  
 Person1:        I don't think it's broken .  
 Person2:well , if it's not broken , then you need to learn how to vacuum better , because it doesn't look like you've vacuumed for ages !  
 Person1:        fine . I'll go vacuum . Let me know if you need any other help .
