Pineapple Hospitality

I was just walking down the hall in the Administration Building on Campus (where I work) and I heard this lady say, "Did you know that the pineapple is a sign of hospitality in the East?" We talked about that in class last week, so I was surprised to hear it so soon when I have never heard it before. Maybe she heard it from someone who was in our class and them sharing it is passing on folklore. I think I will tell someone else today to pass it on as well. :)
