Sometimes you just wonder what went wrong…

You will understand better after reading this story.
"I’ll be 72 next year and my wife will be 68. My first child is 45. But something unfortunate happened to me after a marriage as old as 50yrs! I had a… it wasn’t a fight and I wouldn’t call it a quarrel either. I would rather call it a little misunderstanding over our third son’s new business. He was planning to embark on a business, which I supported but I just can’t explain why my wife insisted that he mustn’t do it. I had to be firm this time around because it was about the third or fourth time she exhibited same reaction.
But all I asked was “But WHY?” I don’t think I’ve completed that question when I suddenly heard a smash on my head! I went blank! Not until I regained consciousness in the hospital, feeling very serious pains all over my head and face that I knew what had happened to me. My head and face had been covered with stitches! Why? My own wife smashed a bottle on my head?! It had never happened before and I have not stopped wondering what from hell came over her!"
Mysterious, isn't it?
