Several people have indicated that my last post was pretty technical, so let me see if I can explain it differently…

It’s like this: Imagine that Daddy and I are walking down the road. I have a notebook that I can write stuff in.

First Daddy and I walk past house number 64. Daddy tells me to “Write down the number of the house we just walked past”, so I write “…the number of the house we just walked past”.

Then we walk past house number 66 and Daddy tells me to “write down the number of the house we just walked past”, so again I write “…the number of the house we just walked past”.

THEN we walk past house number 68 and Daddy tells me again to “write down the number of the house we just walked past”, so then there’s a plot twist and I write “…the number of the house we just walked past”.

Finally we walk past house number 70 and Daddy asks what I’ve written down so I look at the notebook and see:

- …the number of the house we just walked past.
- …the number of the house we just walked past.
- …the number of the house we just walked past.

so I look at the number of the house we just walked past and see that it’s 70. I say to Daddy “70 70 70” and he gets annoyed.

Now replace me with my computer and Daddy with me and that is what I was talking about in the last post.
