Am I being paranoid?

My husband works night shift and is gone from 5:30 PM until he returns 6:30 AM.

My husband was putting his work stuff in the car and me and him were putting our trash and recycling bins out, when a big gray truck stopped in the road in front of our house. Was idling there for about a minute, (60 seconds is pretty long time to be parked in the middle of the street), then sped off.

Then, not even two minutes later when I’m saying bye to my husband for the night, the truck had turned around and driven down our road again slowly.

My husband shot him a dirty look and the truck went off in the opposite direction toward the neighborhood next door.

Now I hate being alone at night (pregnant and we have a 4 year old) so now I’m all wound up and anxious about why a truck would be idling in front of our house and driving in a circle back around.

Am I being paranoid?
