I'm going to call out my friend for faking problems
What makes you think he's faking problems?
He posts about how horrible his life is when in fact he was leading a very charmed life
I understand, people are expected to try and be authentic. It's not nice to lie to people.
So I should let him carry on with his fake life?
As long as you do it in a calm manner, I can't see why calling him out is a bad idea.
