Two Speeds

When I perform stand up comedy..I undergo the same preparation prior to each show..I present material that I believe is funny..I rehearse a lot..experiment with word groupings

I will use the same material and get a roaring response..use it a second time and feel like I am getting
dead air..

It is a thoroughly raw experience..it is only acceptable for my friends to be affirming or neutral because I will be already be reliving everything and   wanting to change it all..
