Manners of Gift (more appropriately translated as Gift Giving Etiquette) is a red book added in version 1.47 of Elona+. It talks about the appropriate manner of handing gifts to other people.
Gift Giving Etiquette Written by a travel-loving merchant Ever find yourself stumped on how to give a gift to someone? You can't just hand it to them thoughtlessly, right? Now, while there's no need to be overly concerned on how you give gifts to those closest to you, it's important to keep in mind that many people care just as much about the presentation of a gift as they do the gift itself. In most places, proper etiquette is to place the gift at the feet of the other party - anything else is considered rude. Of course, such extravagant measures aren't needed when exchanging gifts between family. Be careful though, as in some places (such as Asseria) this manner of giving gifts is seen as rude. In Asseria, people are willing to directly accept gifts even from strangers. Gift giving etiquette is different everywhere. Whenever you're out exploring the world, you should always familiarize yourself with the local customs.
