Fog

Looking up, there is just fog in the sky no clouds nor is there  a bright star floating in midair. And now I look straight ahead cars slowly disappearing into  thin air, almost like being swallowed by the thick grey fog. Slowly as I get deeper into the fog I can see things that i couldn’t before and then i begin to wonder would i be visible for other cars behind me? The fog was so thick that I couldn’t see the path in front of me.
