That's not always safe either. I had a lightening fireball come right through my dining area French doors, about 10 feet from where I was sitting, curved and got sucked right into the electrical system, and then exploded, shaking the entire house. $15, 000 worth of damage 16 years ago. The soffitt and facia in the back of the house had, what looked like, bullet holes through it's entirety. And a big flume of smoke rose over the house. I watched that fireball coming at me. It looked like a Star Trek battle shot from the Enterprise.
