Whenever someone asks me if I'm done with my Christmas shopping I'll always lie about it.
Why do you lie about it?
Because it's none of their business.
Lying about Christmas shopping doesn't seem like a big deal. It's not really anyone's business but your own. As long as you get it done eventually, it's fine.
Don't you feel good when you lie?
While it isn't a big deal, no it should not feel good to lie. if you are going to lie to people then it should be to keep your privacy safe and not because it feels good.
