My mystery continues. I mentioned upthread that USPS notified me of a package which was scheduled for delivery and that it was from a source that neither of us had ordered anything from. The package arrived today and we received a beautiful Gift Box and a box of Chocolates. There was no gift card and no indication of who this was from. Also, the package was addressed to both myself and Mrs SuperG with our first names. The shipping label says "A GIFT FROM: Thank You For Your Order".
So, logically, if it was from my Secret Santa, she or he wishes to remain truly anonymous but knows us since they know Mrs SuperG's name and the spelling of same.
Therefore, if this was from my Secret Santa I'm letting you know that your thoughtful and wonderful gift arrived and I'll WHarvey know as well.
