Actually, my thinking use to be very weapons, military, war oriented :-) I had a T point that out to me once. But I thought of my head as my "foxhole" and would throw the hand grenade into my own foxhole

Good thing no one else was in there with me! I think I didn't picture anyone in there, including myself, it was more like a "space" for storage or living only it had gotten "messy" so I'd blow the whole thing up and start over with a "clean" space. Kind of like I'd picture moving to start over now I think. Only I'd "get rid of" everything quickly so I could pretend it didn't exist "yet".
I know the brick wall you're talking about, September, I think if I had that again (haven't had one for a long time) I'd try to "own" the wall and that would help me either dismantle it or do home-improvements to it to put in a door, LOL.
