I showed my teacher the framework of my big thesis, and the teacher sent it to me at 3 pm. How can I thank him? But I still have a little paper I want to invite him to read. I will graduate soon. Do you want it? Pick up some fruits and thank others. Or invite you to dinner. Around three o'clock, really ...

When delivering fruit, or when eating, take the opportunity to present a small paper and see the teacher's response. Willingness is good, and teachers also like good students to trouble him; It doesn't matter if you don't want to. You still have to say thank you to him (don't make it look like extra help for a small piece of paper).

Above, it is not awkward to solve problems in a friendly atmosphere.
