A few years ago now but I've never forgotten. The OP was heavily pregnant and had given her DP and his friend a lift home after they'd been out drinking, driving down country lanes in the dark. The drunk friend kept punching the back of her driver's seat really hard for a laugh, hurting her, obviously upsetting her and distracting her whilst she was trying to drive. She was upset that he'd done it, wouldn't stop and her DP didn't step in.
The replies were ridiculous- she was being pathetic for expecting her DP to speak up, why couldn't she fight her own battles. And she really shouldn't be driving if she is so easily spooked, if she can't cope with a man punching the back of her seat hard whilst she's 8 months pregnant without getting distracted how would she cope with a crying baby in the back? Utterly batshit.
