Now you see it, now you don't

What you are seeing is an actual eye exercise. I hold a straw. DH has to look at the middle part of the straw and place the wooden skewers at the same time into the ends of the straw. He has three straws of varying sizes. This is the largest. He cannot do it. Neither can I. It is far far harder than it looks. Try it! You will be amazed at your ineptitude. I was amazed at my attitude when I couldn't do it. It is diabolical and frustrating. Like DH thinks about me sometimes.
Maybe the point is to try it but not actually do it. Maybe it's just to make you crazy. Well, then it worked!
We have been watching the Olympics and I think of how many many hours/days/weeks/months/years the athletes have trained and then something goes terribly wrong in the pool/on the bars/on the horse/on the gym floor/the court/the arena/the track and you just crumble and break down and cry OR you hold your head high, exhibit sportsmanship, smile, wave and perhaps try again next time. Every one of us has disappointments in our lives. Every one of us has had that "moment" when you can choose to keep going or fall apart. I have fallen apart, only to discover that something better was right around the corner. I admire DH for his ability to keep trying to do these eye training things (and there are lots more fun things to torture his brain and eyes with!) even if  a) it doesn't work the first or second or twentieth time  b) you think its doing nothing at all.
