Anna: i tried. I went to talk to them but the music was so loud they didn't hear me banging on the door! 
Bill: so what did you do then?
Anna: nothing! i went back home
Bill: you should have rung the police!
Anna: yeah, maybe 
Bill: what if they keep doing it?
Anna: i guess you're right
Anna didn't sleep well because her neighbours had a party last night. Next time Anna might call the police.
