I have a deck I built out for my SVP 2 or so years ago that I reused, which is good because being in 4 days of offsite meetings (while sick/recovering) really just jacked the last 2 weeks up. But I was still nervous because I'm never quite sure what I'm going to say. The slides are always a framework, I never read them. And when I see people's eyes start glazing over I start storytelling.
I must really a show off at heart, in spite of being an introvert, because I love to get the visceral reactions people have when I tell a story well. And for me telling a story is a very interactive thing. I don't know if it's growing up with a storyteller father (though that wasn't a skill he showed us as kids), being part Italian or watching C3PO in Return of the Jedi that informs my style more. I had to stand up in front of everyone to talk, even though all the other presenters tend to sit. I also warned them that I wave my arms around a lot. Because it's true, I do that. I can't really help it, and I'm not sure I'd want to.
I did manage to drop a few jaws with the amount of work the team does and a couple of stories from my time at the office. I answered questions, digressed a lot and did an ok job of keeping everyone entertained with what could be a very dry subject. The best part was when I pulled a small curtsy at the end. I have no idea why I did it, it just felt like something that would be funny. And it was - I got actual laughs. So it really was like elementary school.
