Those people in front of us are making so much noise. it's so inconsiderate. 

Don't worry about it. It's not such a big deal. 

Oh, I can't hear a thing. Excuse me. Can you keep it down?

 Sure. Sorry about that. 

Someone's phone is ringing.

honey, I think it's your phone. Did you forget to switch it off?

 Oh, no, you're right. That's so embarrassing. 

Do you mind keeping it down? I'm trying to watch a movie here.
