Here’s a rearranged version of the conversation:

1. You look tired. What’s the matter with you?
2. I’m having a headache while there’s still lots of homework to do.
3. About the homework? Listen to me. Your brain works similarly to your muscle. Your hands will be exhausted when you carry something for a long time, and your brain will cause you to have a headache when you let it think too much.
4. Forget about the homework! You need to take a break and relax now.
5. No, I have no time to relax, my friend. I can’t help thinking about it.
6. No. You really need to go out for a walk and breathe some fresh air. Give it a try!
7. Wherever you like, to a café, the park, or just walking around.
8. But where will we go?
9. Thanks for your advice and explanation, but it’s hard to ignore these stuffs. I’m not in the mood of doing anything else. Just leave me alone.
10. To the café then.
