[header] How to meet and greet royalty [title] Stand when they enter the room. [step] This is one of the most important things you should do when in the presence of royalty. If you are waiting in a room for the queen or other royalty to arrive, you want to be sure to rise as soon as you see them enter the room. 
This is a show of respect for their position. If you happen to be somewhere in public, perhaps sitting in a park, when royalty walks by, be sure to stand up in that situation as well.
