Not So Perfect Speech

I like to speak in front of an audience, and had that opportunity this week. I was the guest speaker at a woman's group of 15, about hypnosis and hypnoband. The few days before the speech, I had one crisis after another and my time became scarce. The only preparation time I had was as I was on the road driving. On the day of the speech, I expected to get out of work early and write that speech. Of course that didn't happen. Luckily I had handouts and flyers already printed, so the bulk of my speech, I decided to just do a quick overview and then questions and answers with a demo or two at the end. I did as expected and the group seemed to like it a lot. The demos were geared towards audience participation, and about half did participate and had an enlightening experience.
Where it went wrong was that I opened my mouth really wide, and inserted my foot completely. Basically I reminded a woman that she was NOT slim and trim. Ya know, when those words somehow just fall out of your mouth, there's nothing you can do but apologize. I spose some would go into denial, as standard for many politicians, but the cat was out of the bag and I just had to let it go. Oh well. So much for thinking/planning before I speak!
