Metaphor or Simile?
To laughter and contempt; that she may feel
How sharper than a serpent's tooth it is
To have a thankless child! Away, away!

Okay i understand how it would not be a simile but how would it be a metaphor??
What two things are being compared?
serpents tooth and thankless child?
Right. And without the use of "like" or "as," it's considered a metaphor.
