从所给的句子中选择恰当的句子完成下面对话（有两项是多余的）

A：You look unhappy today．
B：Yesterday when I came home，I found my parents looking through my schoolbag．I got very      angry．Shouldn’t I keep my own secrets?
A：Of course you can keep your private (个人的) ideas and secret things．
B：No，but I shouted to them．They didn’t say a word．They just kept silent．
A： In fact，your parents shouldn’t look through your schoolbag．They should respect your privacy （私人权利）．    They want to make sure you aren’t in any trouble，and they want to understand your life and study better in this way．Maybe you hurt your parents．
B：I agree．
A：Say sorry to them．Try talking to them more．Let them know what you are doing，so that they won’t worry about you so much．
B：OK．I’ll do as you told me．
