You are merely casually friendly with these people, and the only reason you would mention this to Sue would be because you believed that watching gay porn—which you assume Matt is watching by himself as a secret from her, despite not mentioning any evidence that supports this belief—is a sign that he’s about to leave her for a man. You are more than a few steps ahead of yourself! Invest in a bedroom fan or white noise machine and do not concern yourself with the pornography your neighbors watch.
