Yes. And, that implies that you were not interrupted during that process!
A simple social rule that usually works is, "Never interrupt." This implies, of course, that the other social rule of "Provide others with period chances to speak (pauses, questions, etc.)" is also followed. Interruption is more difficult and nuanced. We all agree that we may interrupt anyone at any time if we notice a fire in the building. But, it gets more difficult from there.
In some cultures if you wait for the pauses, you will never be able to speak. I found this to be the case while living in Eastern Europe. The people there generally keep speaking until you interrupt. It's not considered rude though. They just assume you'll interrupt when you have something to say. If you don't interrupt, they'll keep talking.
