question:
Person1: why are you in such a good mood today ?
Person2:well , yesterday , I decided to face my fear of heights .
Person1: I didn't know you were scared of heights ! Was it really bad ?
Person2:let me put it this way . I've never seen a professional sorts game in a stadium because I could never get myself to walk to the top of the stairs to sit down .
Person1: so what did you do about it yesterday ?
Person2:I went sky-diving !
Person1: you're kidding me ! that sounds really scary !
Person2:It was scary , but it felt great , too .
Person1: weren't you scared ?
Person2:of course I was scared . But I had an instructor that went with me and that helped .
Person1: so have you cured your fear of heights ?
Person2:I think so . After I jumped out of the plane , I realized that I should just enjoy life . Worrying about it or not doing things out of fear is just plain silly .
Person1: I'm impressed .
Person2:are you scared of anything ?
Person1: well , sometimes I get scared when I'm in my apartment all by myself .
Person2:what do you think is going to happen ?
Person1: I always worry that the door is unlocked or that a window is open and that a stranger will come in and steal my things .
Person2:it sounds like you just need to be more careful .
