Why did you get up late this morning?<br />I went to bed late last night.<br />What were you busy with?<br />I did my homework at 8.30 p.m. and finished it at 10.30 p.m.<br />It was late.<br />How was your sleep?<br />Bad.<br />The people next door played loud music.<br />I couldn't sleep.<br />That sounds terrible.<br />If they do it again, I will talk with them.
