My AV is the voice of my Beast, and my Beast sure as hell ain't my inner child, lol. To each their own though.
I haven't ever humanised or given a personality to my Beast/AV. Slippery slope in getting cozy or otherwise feeling "satisfied" with my AV.
I'm indifferent, mentally and emotionally, to the nth degree with my AV. I use AVRT to recognise it, and then I forget about it, and get on with whatever.
AV is a perfectly normal part of my thinking of course, and I don't see any need to give it any recognition whatsoever except its the mouthpiece of my Beast.
