Strong coffee<br>I was feeling rather tired. So I decided to make some coffee. I put the k cup in the machine and made it strong. When I tasted it it kicked in instantly. I was then awake all night.
I couldn't stay awake, so I drank coffee.
The agent did not state that they could not stay awake, just that they were tired. I think it was difficult for the system to understand because it included key words restated from the context.
