Dear Tiw,
I understood your apology for us.
First of all, you make more communicate us.
You can say "Hello" and "Bye".
You should join to my lab every day.
You should talk with my students sometimes.
You are always too silent.
You don't need to use good English now.
You should consider more talks even bad English.
I also understand your poor knowledge and skills on research activities
on mechanical engineering and materials engineering.
Did you try to improve yourself by now in Japan?
The other students are doing their best to improve theirselves.
Do you think so?
Don't you feel like this?
Don't you see their behavior?
I can understand your difficulty to give a talk on experimental results.
I explain how to do that in English, so you cannot understand what I talk.
If so, do you study how to do that in any websites or textbooks in Thailand language?
I know that you have given a talk to your professor before.
You can make any slides for presentation.
Do you mean you can make any slides in English?
If so, you don't need to make English sentences in your slides.
You should put some words and illustrations to explain what you want to show.
Here you write your message as Email in English.
Of course, your English was very poor, but I understood what you want to say.
This means that you English capacity is good enough to make English slides.
I think your English may be better than Oshima and Takahashi.
They can do their seminar.
This means you can do, too.
Here you said many "I cannot" and "I don't know".
What you cannot?
What do you know?
You should classify what you know and what you don't know.
You should classify what you can and what you cannot.
I thank you don't know yourself what you can and what you cannot.
At least, you should talk with other students or Yamashita sensei
what you will do in your seminar in advance of your turn.
Less communication does not make any sense.
You understood well importance of communication from this issue.
Anyway I'm afraid on your mental health.
Don't you feel depression?
I'm not sure you can enjoy your life in my lab?
I feel you have too much difficulties here.
I don't think the best way you continue to study here by May.
Of course I follow your decision just now.
Regards,
Makoto Nanko
