Ah yes, telepaths. The ones who believe they know more about you than you do.
I've had one Christian friend insist that I must have chosen to be bisexual or been tricked into believing it somehow, despite my telling him I made no such choice and wasn't prompted by anything. In a conversation over the Internet with another said "telepath", I mentioned I was bi and was greeted with "No you're not. There's no such thing as bi." Said person then recommended I read the Quran in order to understand better.
Another frequently-quoted statement along similar lines is used in response to deconversion stories.
"You were never really a Christian to begin with. If you were, you would know God's presence/have a personal relationship with Jesus/be filled with the Holy Spirit and would not have fallen away."
