After you use your mobile phone, you have to do your homework. At this time, if someone asks you to borrow your mobile phone, how should you politely refuse him?

If you use your mobile phone to make a phone call or send a text message, say that your phone bill is running out or you are waiting for a call. . .

If I borrow your mobile phone to play games, just say that the battery is dying. . .

If I borrow your mobile phone every day, just tell him: I'm sorry. . . Then go back to your work and ignore him until he knows his interests. . .
