According to Ari, everything I say is a blatant lie. Or at least that’s how it feels to me. I could be sitting on the couch, and say to him:

“I’m sitting on the couch.”
He would reply:
“No, you not sitting on the couch!”

He loves to disagree with me. Here’s another example:

I mean, clearly we’re at the grocery store and I am objectively right. Unfortunately, that doesn’t matter to him. I just don’t know how to respond without getting into a full on semantics argument.

If I say “No, we’re at the grocery store” he’ll just argue that we’re not. But I don’t feel right about acquiescing and saying “You’re right, we’re not at the grocery store.” Because we are!

What is an effective way to deal with this dissenting behavior?
