<p>Yoshi, I have long ago and then continuously recognized this duality in performers. There are, of course the bold, loud, “look at me”, or simply I love entertaining you and I know you love me - type personalities that one would naturally expect to be an entertainer. Then there are lots of folks at the other extreme who are quiet, even shy who use the stage to “let go” and express themselves. Of course, this represents a spectrum and folks fall in all along the way. But, to your question - it is not at all unusual for persons that seem shy to shine on stage.</p>
