The Lightbulb Moment

I have had the following conversation twice now - with two different people, at two different times - both at the tail end of a heated discussion where I've been accused of always over-complicating everything. I typically offer the following as a refutation of their perspective, but as you can see, I have been completely out-matched both times:

"I can admit that I have a tendency to sometimes over-think things and present them in a far more complex manner than is necessary, which is why we have these discussions - I'm not infallible. That said, is it possible - just possible - that you may occasionally over-simplify complex things?"

"No. Not ever."
