Bitch Shield.....we all come up against it!! question is; how best to tackle it?
I go for the direct approach, which to all intents and purposes is verbatim the following;
(on coming up against pretty much any bitch shield; lean in and with an earnest smile)
"I can see that being around me brings out the worst in you, so let me stop you now from saying something which you'll probably just beat yourself up about later."
remember, bitch shields are like bullies; they crumble at the first sign of resistance!!
