Such a mama, such a mom, such a mother moment. Here’s Hamlet, sweaty from the fight – she’s given him her “napkin” already but still, he has not wiped his face to her satisfaction.
Some Hamlets will acquiesce to this moment easily, even eagerly – happy to receive an affectionate face wipe from his mother. Others will resist – just the way almost every teen squirms under the moist thumb of his mother.
What happens here depends a lot on the Hamlet and a lot on the Gertrude and whatever relationship they have forged through the rest of the play.
