Spit
We were sitting at a stop sign when it happened.
"Black cat!" Derek yelled. He and Alex rolled down their windows and spat on the payment. Carol and I gave them a look.
"You spit when a black cat passes?"
"Even in the car?"Alex replied, a brick of a boy melting like butter.
"Yeah." The nervousness in his face was new to me so I complied, rolling down the window and spitting.
"That's so stupid." Carol remarked, driving on.
"Come on. Something bad will happen if you don't." She was silent for a moment before the car swerved into the other lane. She screamed and screamed and honked her horn as us kids freaked out. She laughed, straightened the car and went on. The rest of our trip she mocked us.
I don't know what happened that night, but she started spitting when black cats passed afterwards.
