In your email, you had written that Aunt Miwa was in the hospital. I noticed it after a while and told to my mother about it. Please keep me updated. You can write to me in English.
I noticed later that there is a note about Miwa's hospitalization on email and let my mother know immediately. Please keep me updates. English is fine.
I noticed later about aunt Miwa’ s hospitalization written in your letter and informed my mother about that right away. Please let me know if you know further information. It is ok to tell me in English.
I realized, in your letter written about Miwa Obasan who is in the hospital later, and I phoned mother. Please tell me if anything happens. I do not mind if you write in English.
