Possible ball lightning or ?

My wife's turn to experience the weird. This morning my wife and I went into town for a few groceries. We returned in the early afternoon as storm clouds rolled up on the horizon. Its Labor Day what more is expected. It began spluttering rain shortly after our arrival and it rained off and on for the rest of the afternoon. There were several peals of thunder and lightning but nothing intense. When we arrived at home my wife sat down at the kitchen table and announced she had paperwork she had to finish. So I took the hint and took the dogs with me into the Library with the computer. An hour or so later as I was catching up on some correspondence I heard my wife call me. I went to the kitchen but my wife said, "Forget it you're too late". "Too late for what?" I replied. She then explained that as she was working on her reports she noticed the overhead lights were flickering (directly over the kitchen table are two 1-00 watt equivilent coiled florescent bulbs (the kind our dimbulb government insists we use). My wife figured either they were about to go out, or the electricity was about to go off (Which it does,here,frequently). Looking up towards the overhead lights she saw a bright ball of light bouncing about 8 ft. high in front of the kitchen fireplace. It was passing east to west. She called me, but I was too slow getting there. The ball passed into the cupboards on the western wall. As she discribed the light, I immediately thought "Ball Lightning". I have read a good bit about ball lightning but I've only seen it once and that was around 50 or 60 years ago.The ball lightning I observed came swooping in a low curve out of the sky. It was about the size of a basketball and glowed with static electricity as it bounced across a neighbors backyard and across my parents backyard and fizzled out on a barbed wire fence seperating the backyard from another neighbors garden area. I think the ball lightning that I witnessed so long ago would have left scorch marks on wood. But this small lightball my wife witnessed passed into a wooden wallcupboard with not a trace of where it entered. So I'm not certain what she saw. I'm sinply reporting it as it was discribed to me. I wish I had seen it.
