Ya, I have thought about it, and when she arrived yesterday and we were alone at the beginning with them completely on display, I actually started to say something, but then I chickened out. It would have been the perfect time.
I know it seems bizarre, but it's just something that has always fascinated me how different they are every time. My wife's, for example, look exactly the same every time I get a glimpse of them, and so do my neighbor who I see at least once a year if I go visit in her yard at the perfect time. But my wife's sister...very different every time.
There have been many times that I have wanted to say that I have seen them countless times and I was wondering if I could just have a full view.

But I am too chicken. Who knows, maybe she has been waiting for me to ask for the past ten years...
