If an acquaintance made sure to inform tu that tu have a "dark" personality, how would tu react?

I only ask because this happened at me during art class yesterday and today.


So this is what I would do... Er, did, I suppose I ought to say...

This guy and I were making unproductive conversation for no real reason whatsoever when out of nowhere he tells me in a very serious tone "You are REALLY dark, tu know."

And I knew what he meant, but I couldn't prevent myself from saying, "Really? Most people tell me that I am rather pale..."

And he chuckled a bit and went on saying, "No, your personality. You're just so... dark."

And I seriously had no idea what to make of that so I just kept on working...

So out of reason-less curiosity, I ask all of you, what would tu say?
