Today I recieved a letter from my younger brother which read he would go to study in America on March, 13th. Would you please let me take a leave for two days from March 12th to March 13th? Thank you

Dear Mrs.Wilson,
I am going out for shopping. I will return your borrowed books by the way. Tracy left a message. The meeting in the coffee house had been cancelled. I had already told Susan. See you later!
