I lied to my sister about why I failed a class and regret it deeply. Do you have any advice?
Why did you lie?
I don't think I can bear her anger after she finds out I failed all my exams.
I'm sorry your exams didn't go how you would have liked, but you shouldn't have lied to your sister. You can't fix something by lying. Be honest with her and tell her the truth.
I'm worried that if I tell her the truth, she'll be hurt and she might cry.
She may be upset with you, but if she finds out the truth on her own and then she'll be even more mad. The best thing you can do is be honest and apologize to her, and she's likely to forgive you more quickly.
