I'm going to lie to my dad about where I met someone
Why do you want to lie to your dad about how you met?
Because he will not approve of us dating. He doesn't like my new friend.
It's okay to keep things to yourself if you know if is going to cause a wedge in your relationships. As long as you and your new friend are happy and comfortable with how you met, you shouldn't have to tell your father.
Cool, I doubt he will find out anyways.
So what do you like about your new friend? Do you guys have some plans together anytime soon?
