> I’ll just assume you’re offended because you’re old.
I very strongly suspect I'm younger than you. And I've no personal interest in artistic pursuits, to be explicit.
The only reason I took offence was that you were, in short, acting offensively. Even shorter - you were an asshole.
In the longer - you were telling people who wanted to pursue art that they were presumptuous for daring to do so because they weren't the right age in your opinion. That far exceeds presumption and veers directly into arrogance, as I mentioned earlier.
> Prove yourself or deal with mediocrity
We are nearly all, in the scheme of things, mediocre. That's just how normal distributions work.
But, you don't have to shit in someone else's Weetbix just because you're feeling your age and Scrooge's "Bah humbug" makes more sense than ever.
Just stick to yelling at those damn kids to get off your damn lawn.
