I'm sure I have more if I think about it, but the first that jumps to mind is that I had a bottled fizzy water I was drinking on the table next to me. I tend to talk with my hands (especially when I'm anxious), and I hit the water bottle. The cap wasn't on tight, and the bottle flew across the room, spilling a bunch of water on the carpet. I grabbed some tissues and frantically went to clean it up, and my T said not to worry about it, that it was just water and would dry.

In related instances, a couple times, I've gone to take a sip from the water bottle, and I guess because it's carbonated, some of it somehow flew up into my nose. Maybe I need to start drinking noncarbonated water at sessions....
