Chopping vegetables, yes. But when the fire is on, or there's a frying pan, I wish everyone would leave the kitchen. I don't want to be responsible for any burns or accidents. Now that I think about it, when I'm holding a sharp knife I also want everyone away. My fear is that a chatty guest who's not paying attention will walk into the point of my knife (and yes, because of that fear I'm constantly worrying about where the knife is pointed, but still... that's brain cycles I'm not able to spend on actually cooking).
