I once almost ruined my husband's masters thesis presentation. While he was giving his presentation, I had a bad coughing fit. He--and everyone else--stopped to make sure I was okay--and then he couldn't focus on the rest of his presentation!

Oh no, what did you do?

I started coughing--badly. He and everyone else stopped to look at me and make sure I was okay. He was so distracted after that!

Don't worry, from what you said it doesn't sound like you almost ruined it. It wasn't something on purpose at least.
