No, “yeah whatever” is 100% the correct response.
Some older people think it’s just open season to spread all kinds of false garbage about younger generations and the second we dispute it we’re “disrespecting our elders.” They’re only proving the point. They can dish it out all day long, but they can’t take the heat. The lesson is, don’t be that way when you’re older. What’s changed is that we have internet anonymity now. What people thought 40 years ago, they can now say behind a CR username. Which brings us back to the OP, I guess.
CT, I’m not talking about you anymore, by the way. Your comment was not that big of a deal.
