I spy with my little eye

How observant are you? I guess on a scale of 1 to 10, I'd rate myself a 7. I tend to notice things, but I sometimes can't quite say what it is that's different until I think a little longer. But, that' s if it's something that doesn't occur very often . But, what about everyday things? Things that you see or do everyday? Here are a few examples:

1. Without actually doing it, do you use your right hand or your left hand to button your shirt/blouse?
   
2. Do you unbutton your shirt/blouse from the top or bottom?
3. What numbers on the phone are not associated with any letters of the alphabet?
4. If you had to change the tires on your car, which way would you turn the nuts on your wheels to unscrew them? Clockwise or anti-clockwise?

But, no matter how observant I am, I think we guys suffer from some kind of optical disease. I think it's common knowledge that men can be quite blind sometimes when it comes to looking for things. I read about it in books. I've even seen it in a comic strip once. Heck, I've had personal experiences of it myself. On a number of occasions, my wife asked me to find things and for the life of me, I just couldn't find them. And then she'd go look for it herself, and she'd be out 5 seconds later with the item in hand and a look that says 'look what I found'.

I say, why ask me if she can find the thing faster, right?
