@askvinh: If you want to stop being interrupted when you pause, the key is to be "mid-gesture" when you pause. Most people when they talk, they look and sound "done". So when people interrupt you, it's not because they're being mean, they actually think you finished your sentence and that they can start talking. So the key to fixing this is to be gesturing mid-sentence or when you pause so you signal to people that you're still going!
