Back in the 90's I was doing HVAC. A co-worker and I often did side jobs for extra money.

One weekend, we had some work adding a couple of vents to a log cabin. The young couple had a newborn and were doing some home improvements. There was plastic draped over most of the kitchen and living room to prevent dust from getting all over everything.

We completed our work, got paid and were saying our goodbyes. The couple was also leaving to run errands, with the newborn in tow. When we got to the door, I turned around and told the man he should move the plastic away from his chandelier. He said it wasn't a concern, because it had been over a week since he put the plastic up. But he said if it would make me feel better he would move it.

Before he could get over to the chandelier, the plastic burst into flames.

He asked me how did you know that? I told him that it wasn't me, that someone was watching out for him and I'm a conduit like that sometimes.
