　　I hope you will understand me and excuse me for my absence . The reason for my absence was that I had an engagement with some friends and , ignorant of your visit , accompanied them to the cinema . Besides , not until nine o'clock in the evening did I come back . Therefore , it's not in my power to arrange time to meet you .
　　Naturally , I hope you won't leave the city this week so that I can call on you . I shall be obliged if you will kindly tell me when and where you are at convenient , In that case I can take you to some places that may interest you . I hope to see you soon .

Sincerely yours ,
