I'll add my reading to this, and I hope Milfoil that you find it quickly!
Using my Hanson Roberts:
Where will Milfoil find this missing object?
2 cups rx. which makes me feel like it fell out of a container.
What is to the right of this missing object?
4 cups rx. things hanging upside down? or perhaps things that are turned over?
What is to the left of this missing object?
tower. something that is broken.
What is below this missing object?
the moon.
now, the interesting thing is, when I went to turn over this last card, (the moon) i inadvertently turned it over differently (not meaning to, till i had finished turning it over. this card, if it had been turned over correctly--like I normally do turn the cards over, it would be reversed. but, I feel there is a reason for everything! so I will read it upright. I think this is saying that either it is near a light source or at least something round and bright. my eyes are drawn definitely to the moon, and nothing else in this card.
I, too, am seeing that I turned over two cups--which makes me feel like it is tied to water. so I would also guess kitchen or bathroom. Then, also the moon card is a water card as well--so that is 3 water cards! the tower is a fire card--and while it is not necessarily a bad card, it is a card of changes. so I am strongly thinking kitchen, and stove comes into my mind. I strongly feel (and hope) that it will be found among something in the kitchen--perhaps soemthing that Milfoil cooks or prepares over fire?
at any rate--even if I am 100% wrong, i do hope she finds it soon.
GOOD LUCK, MILFOIL!
