Some examples:

In fact "Volder" doesn't exist

Yeah, I never used it, I'm not sure why you're telling me this. You're telling me what I know as if it's new information.

You're thinking of "Voler" which translates to Fly,wing,plunder or steal.

Don't tell me what I'm thinking of.

watch you tongue.

Watch your tongue isn't a friendly reminder, it isn't a "I would apprechiate it if we could stay civil", it's a threat and a lecturing. It always comes from a place of authority, and not a place of equality. Which is fine with kids. But I'm not one.

You just got hung up on the actual meaning (That Riddle was wrong) and missed the point.

Again telling me what I think.

How can you get a "tone" from text on a screen? If it seems condescending it's from your interpretation.

¯_(ツ)_/¯ I don't know how to explain it without sounding condecending.
