I want to buy a boat. What should I consider?
user
In what way? Do you mean a rowboat? A fishing boat? A sportboat?
assistant
I'm not sure yet.
user
Ok, how about we think about the characteristics you like and don't like about boats?
assistant
I want my boat to be somewhat fast
user
That sounds good, many boats are fast.
assistant
Like what type?
user
It sounds like you like the idea of speed but you don't want to have to race the whole time.  Maybe you like the idea of having speed and then stopping to go fishing, or maybe you want something that cruises?
