I have LOST MY MIND !!

So yes it is official that I have lost my mind. Today my MIL and her husband took me to lunch for my birthday and she gave me 100.00 just like always. After we were home for a while I decided I would go buy flowers to plant with some of my money. I took 40.00 and put it in my pocket(I thought) and went and put the other 60.00 up. On my way down the road I reach in my pocket and it's not there and it's not any where to be found. I have torn my house up looking for the money. It's not with the other money and I completly cleaned out my car and it's not there. I'm so upset that's 40.00 down the drain. Hope your day was better. I'll talk to you tomorrow.
