If your name is Serenityrose and someone asks after your name, you can of course just tell them what it is. But sometimes that isn't so easy - what if it's too loud, and you don't understand them well? Or what if the other person is so far away that you can see them but not hear them? In these situations, you can communicate your name in so many other ways: you call spell it, sign it, or even use a flag to wave it...
