I think my mom thinks she caught me, but she's wrong. And she almost caught something else.
Why do you think you've been caught?
I believe she has and I don't think dad has seen it, because if he did, I would probably be in a lot of trouble.
If you truly believe you are in the right, then it's okay, but if you have done something wrong it's also okay to accept that and take responsibility. I would take a look again at your actions and if what you are doing is wrong, then you should stop and rectify the issue.
I don't care. I'm going to keep doing it while they aren't looking.
If you think you're doing right, you don't need to hide it from anyone. Be honest and think about your actions and their potential consequences. I believe you'd make a right decision.
