Klaws is correct. The pineapple is the colonial symbol of hospitality. I've always loved that symbolism!
Now, if you want to go in a different direction, think about what you would do to show hospitality to your guest. Are you inviting her to lunch? Or to brunch? Is this a party, or a celebration of some sort that you have included her in?
Did I give you too much information, or not enough? Hmmmm?
Seriously, if I've confused you with this theme, just PM me. Or we can all hash it out on this thread!
