I agree with you.
I also have something to be shamed for.
I saw Blackmore slamming his guitars on stage and I was curious about it, so I
took one old (unuseable :)) acoustic guitar from my friend and slammed it.
I don't know what I expected, but I felt "****ty" after that :(
Now, I can't understand Blackmore (and all others who break guitars) because they
"bite the hand which feeds them" and the guitar is noble instrument, it's a sin
to do such a thing.

Don't try anything similar :)
