Answer 1

Humans have evolved to pay a LOT of attention to what other humans are saying and HOW they are saying it.

If someone is sick? You want to hear that and move away from them.

If someone is lying about wanting to stab you? You want to hear that and not be stabbed.

If someone is getting mad at you? You want to hear that now so they don’t stab you later…
