Thank you for your polite male.
I didn't notice your male at that time, but later I found it.
I think learning Japanese might be difficult, but I wish your improvement in Japanese.
Feel free to ask me anything when you want.
In these days I noticed your email (or letter), thank you so much for the effort of writing it. Learning Japanese is very difficult, so good luck with that. If you have any questions about, feel free to ask me aytime.
