Input:  Person1:       good morning !  
 Person2:good morning , Gav ! Did you sleep well last night ?  
 Person1:        I slept like a baby . I fell asleep right away last night , didn't wake up once , and didn't have nay nightmares !  
 Person2:that's great news ! You look much more relaxed than you did yesterday .  
 Person1:        I feel much better , but I'm still worried about something .  
 Person2:what's that ?  
 Person1:        well , I have to drive to school for a meeting this morning , and I'm going to end up getting stuck in rush-hour traffic .  
 Person2:that's annoying , but nothing to worry about .  
 Person1:        for me , traffic jams are quite stressful , because I'm pretty impatient . How can I prevent myself from getting stressed if I get stuck in a traffic jam ?  
 Person2:just breathe deeply when you feel yourself getting upset .  
 Person1:        Ok , I'll try that .  
 Person2:is there anything else bothering you ?  
 Person1:        just one more thing . A school called me this morning to see if I could teach a few classes this weekend and I don't know what to do .  
 Person2:do you have any other plans this weekend ?  
 Person1:        I'm supposed to work on a paper that'd due on Monday .  
 Person2:try not to take on more than you can handle .  
 Person1:        you're right . I probably should just work on my paper . Thanks !
