Leaning Forward

I dont know how to explain it.  Ya know how you are sitting in your "comfy" chair? But instead of settling in and getting comfy you are - "On the edge'' Maybe like you are anticipating something?.. Thats the way BOB sits.. I am constantly on alert.. " Why?. What.?." did I miss something? He hangs on the edge- Looks rather uncomfortable and when I ask him of course he says" I'm fine.."
He doesnt look fine.. Nor does he look comfortable. And of course.. I have to "fix" it.   I wonder if I will ever move past the "having to fix it"... I'm guessing Probably not..
OY!
