Hello!
I see.
How are you going to spend your winter vacation?
Thank you.
I still study music theory.
I haven’t made up my mind yet.
Thanks for worrying about me.
I am a weak person.
Therefore, I must become strong.
I received your Christmas present yesterday.
Thank you for a very wonderful present, and please tell your mother thank you.
No problem.
I'm looking forward to getting your reply.
