[usr] I once almost ruined my husband's master's thesis presentation--something he needed to pass to get his degree. [sys] Oh no, what did you do? [usr] 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! [qst] [None] [bhv] I'm in a negative mood, please comfort me.
Don't worry, from what you said it doesn't sound like you almost ruined it. It wasn't something on purpose at least.
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!
