Hit the Road, Toad

There are tiny black and grey pebbles embedded in the palm of my right hand and I hope a car doesn’t come soon.  

"Why am I doing this? There must be some scientific reason behind this—it must be something all ‘grown-ups’ have done at some point in their lives."   

She told me to 'hit the road', so I did.  I was four. 

This is literal thinking.
