Bruh, this isn't an instructional video it's an informative one, there's a difference. You're not giving me a recipe in your bizarre metaphor, you're just generally describing what a grilled cheese is and how it tastes or why people eat it. You're not teaching people how to recreate a grilled cheese perfectly. If you left out the part where you put butter in the pan I would just assume you left out the part where you put butter in the pan, because your audience isn't there for a recipe and doesn't give a shit about every possible minute detail.
