I think I'll step off that metaphor here.
I got to thinking about my disappointments and those things of which I am truly ashamed.
My wasted later teenage years? Disappointed.
My love of 80's metal? Shame. (But I ain't changing - Shout at the devil!)
You get the idea. I can justify my love of Journey ( Guitarist Neal Schon turned down a gig as Clapton's rhythm guitarist when he was 17 so he could go on tour with Santana).
I think the only times I've really been ashamed is when I knew I could do something and didn't. It's like watching someone steal a part of you and not fighting to get it back.
And just so you know I'm giving it my all, I'll admit to liking....no, maybe I won't go that far. Maybe over a beer sometime.
