I'm considering lying to my mom
Thats awful. What are you going to lie to her about?
I'm still trying to come up with a good lie. I haven't settled on one yet.
Whatever it is it's not right to lie to your parents because it's immoral. The guilt of the lie could stay with you for a while.
Well what if I was lying to you before and I actually already lied to her?
If you already told the lie there is still time to be honest and apologize. Parents should be able to trust their children.
