It does seem very inspired lol

I cannot speak for all sarcastic people, I often use it when idk how to properly act. Because I'm awkward AF and socially inept.

But I don't use it to make people feel bad. I make jokes at my expense, not others. As you should.

I think trying to make people feel bad about themselves is more about them being a shitty person and less about their attempt at sarcasm.

But I also find overly happy and peppy people exhausting and don't like them. And people seek that out. Sarcasm is way more palatable for me.

At least you know you'll never have to suffer through an interaction with them. And if you do, just run away.

That's what I try to do.
