The tongue like a sharp knife... Kills without drawing blood.

My tongue is a knife that is very sharp and you know, it can hurt you very easily.

It kills you to see them grow up. But I guess it would kill you quicker if they didn't.

Did you know the pen is stronger than the knife: they can kill you once but they can't kill you twice.

The tongue deviseth mischiefs; like a sharp razor, working deceitfully.

She may be crazy but at least she isn't you.
