Well, last night I thought it over and realized that my brother would probably not wrap another gift in Christmas wrapping paper and stick it in the Tiffany's bag if it really was something from Tiffany. So I opened it and sure enough - packets of spices and sauces!! haha I knew he would just think "Oh, here's a small gift bag I can reuse" instead of "a Tiffany bag sends a message to expect nice jewelry."
Bless his heart - he gave earrings to me and DD17 because that's what was on his list. Poor DD22 didnt get anything - the box of her gifts didn't get delivered in time for Christmas and I know he didn't get her any jewelry. She's being a good sport, though - plus she knows the hoops I got are really too big for me and I'll "share" them with her!!
Of course, next Christmas we will be ready for him with a nice suggestion for ALL of us!!
