I work with some of them as well (white, childless middle-aged women); when someone proposed resurrecting the company picnic for the employees’ families, one of them snarled, “Only if we can bring our dogs”.
A lot of regrets in some of them, and real bitterness towards younger women avoiding the same path (especially minorities).
Really want to hear a snarl? Say something derogatory about abortion. That will get the old guilt trip running on full octane.
