Observe this sequence from the Sam Taylor Taming of the Shrew (1929):
That non-verbal exchange between Katherine and Bianca takes place after the exchange of these famous (and famously-problematic) words:
The wink, obviously, changes everything. She doesn’t mean what she says—but it’s what she has to say (both because Shakespeare wrote it and because Petruchio and custom seem to demand it.I am ashamed that women are so simple
To offer war where they should kneel for peace;
Or seek for rule, supremacy and sway,
When they are bound to serve, love, and obey. (V.ii.162-65)
I supose, if we consider the Petruchio she’s up against, an ironic reading is, really, the most straightforward!
