Thanks to my Grandmother, I have been drilled with etiquette and know how to set a table with speed and accuracy. I have taken numerous classes on manners and how to present ones self with, also, my Grandmother. As a result several of the requirements for this badge regarding being a guest were review and I was able to prove my proficiency quickly.
The only thing that I had trouble with was... being a hostess. I do not have friends over much, so I was not used to having to play that role. Until around a month ago, I was an expert at playing a Hermit, this badge changed all of that. I now am playing hostess once or twice a week. Which means that I can receive and introduce guests and bid them good bye.
I have had to write a note of invitation for various events. I did this using traditional and modern methods. I think I prefer facebook events :)
The last part was to actually plan a part/event and assume I didn't have a serving maid (that was easy). This was successful - not traditional - but we did have food, beverages and entertainment. Understanding the roles of a hostess for a guest who is staying a few days or more - was something I was familiar with and was able to name those responsibilities without any issue.
