I see a therapist every week who uses a bit of the transactional analysis school of thought to frame things. She has used the analogy of driving before, but in the context of TA it's the inner child who is driving at times. This inner child can be a bit of a dickhead, as children sometimes are, but no one should ever take the child and stick it in the boot as Jack has done in her Stan-like fantasy.
As you say, TCC, it's something that is part of you that needs to be managed. You have to softly, gently negotiate with this difficult part of yourself. Do a bit of coaxing, yet be firm! It's all about the adult part of yourself being able to step in to guide your actions and not allowing your impulsive, upset and damaged parts take over and do a chaos. Stuffing them in the boot will only kick chaos down the road and is frankly pretty cruel. You're meant to approach the dickhead part of yourself with empathy and understanding, not absue them further.
This reads to me like Jack has heard this analogy once and stopped listening halfway through. Instead of learning a new thing about treating herself with compassion to help heal her chaos, she probably started dreaming up a new analogy where she could come across as a badass who dominantes the dickhead in her brain. Oh dear.
Anyway thank you all for being really funny and insightful bunch, have been lurking for so long, it's nice to say hi finally.
