Why can't I say NO...

This time Josh was a wonderful husband and told the ward clerk (or whoever he is) that he had to ask me personally if I would speak in sacrament. He called tonight. I really wanted to say no but deep down I just coudln't bring myself to do it. So, I have to talk on May 31st about using prayer in our daily lives. Any suggestions are greatly appreciated. :) I'm not excited to do this but I guess one good thing out of it, at least for Josh, I can't be mad at him, only myself.
