Can I borrow this magazine from you ? It's really interesting and I can't put it down . I am sorry , but I can't lend it to you now , for I haven't finished reading it . If you don't mind , I can lend you some back numbers to you . That would be very kind of you . By the way , is it a monthly magazine ? No , it is a fortnightly . So , you see , I can get the new one quite soon .
