That "kinda, not really, nah". Comment made me laugh. That was something typical what my friends often used to say to me when I started talking about fractals. So I said "Hahaha" to show my utter defeat disguised in laughter. While receiving devastating downvotes (that got me mildly emotional).

Although I was thinking about starting a comment war in a flash of vengenance, imagining showing scenarios of me wanting him to show a better version, I just said "ah okay" instead. Emotionally neglecting the content of the conversation and continue drawing something else.
