Don't put things on the roof of your car

I put things on the roof of the car daily. I place all items above Cakes's window as I put her in and out of the car. Items can consist of things Cakes has left in her seat such as books, food, drink bottles or things in my hand such as the car keys, my phone (which has my entire life attached to it as I do not carry a bag so I have a neardy wallet phone holder), a can of coke, etc. This afternoon when we were running late to pick Daddy up from the train station I had a clip board with paper, a pen (things Daddy requested we bring) and my phone. I had a jacket on so I had placed the keys in there. When we drove off I heard a clunk but didn't think anything of it. Within the two minutes it took to drive down the road and around the corner I looked over to where I keep my phone (as we were running late I was expecting a phone call from Daddy) and realised it wasn't there. I continued on and went up the next street taking us back home. As I pulled up before our drive way I could see the pen. I searched down the drive way, on the road and in the gutter a few metres down the road. No phone or clipboard. I kept looking as we continued on to pick up Daddy, though with no hope. The entire time Cakes was saying from the back seat "where's your phone Mum" for me to polity reply "I don't know". When I had continued down our street and a few hundred metres along the road I saw a white pile of something, I decided it was mine and stopped. Fortunately it was the clip board and my phone. If I had not been late I would not have looked at the space where my phone normally was, if I didn't have the clipboard I would not have seen the phone on the road and if I hadn't broken the phone yesterday (Cakes and I dropped the phone as she handed it to me and the home key broke) my husband wouldn't have organised a new phone for me during the day. I checked the phone and it seemed fine, up until Daddy connected it to the computer to back it up to put  the information on the new phone. It must have been run over as it did not connect, he looked at the connection and low and behold it was all smashed up. So I would like to suggest Don't put things on the roof of your car.
