I don't think I should lend it to him. Because I am a friend, I don't want to hurt him. Copying homework too often will form a bad habit, so I rely on copying. I always don't want to use my own brain, and my final grades are even worse. I often encounter such troubles, but as long as I say to myself, it doesn't matter, he won't blame you. After all, you'd better not borrow it for his own good.
