I Believe
A way to say you’re super confident in someone, like when your mom says she believes you’ll pass your test, even though you failed last time and you know she’s lying.
My mom said, "I believe you’ll pass." I said, "I believe you’re lying."
He said, "I believe you’re the best." I said, "I believe you’re wrong."
She said, "I believe you’ll win." I said, "I believe you’re stupid."
