The funny point of view is supposed to coincide with the view that you as a child had. But then, how come this, otherwise cool grandma, doesn't feel scared about where your head is?
Grandparents and automobiles fill a big part of ones first memories and your choice of subject is to be saluted. The control of light, as well.
This made me think. I can remember my grandparents car and the way it smelled and that was forty some years ago. It's funny the things we remember. Nice photo of a good memory! (I hope it's a good one for you!)
