I'm going to lie to my friends about a discount
Why would you lie to your friends?
I want to teach them a lesson, they should pay for things instead of using me. They will thank me later.
If you lie about money like this you might not have any friends when you are done. It is wrong to lie to your friends tell them the truth about how you feel.
What I'm doing is not a bad thing, they would still need to pay something.
It is okay to not want your friends to use you for a discount, the problem is lying to them. Friends should be honest with each other.
