FHN:
Instead of trying to manipulate this woman with guilt and shame by saying (and giving her "the look" intended to induce shame/embarrassment):
"When I was a child, we gave up our chairs for adults." I gave her my "You're not slippin' that one by me, honey" look. "I know you know better."
Perhaps following the advice of your therapist would have been a wiser course of action:
Shame is not something helpful in a situation like this. My therapist, Doctor Julia Mohr, who is also a Catholic Domincan Nun, told me shame never works. It only trains a person in appropriate [sic], non productive/destructive guilt.
And, unlike you and your penchant for rudely assuming another poster's emotional/hormonal state, I wouldn't dream of bringing up your entire posting history of attention seeking, self-important threads, because that would be disrespectful.
