Is that why you didn't come to work yesterday?

You can read about lazy loading at: http://en.wikipedia.org/wiki/Lazy_loading.

I didn't know Martin Fowler had delineated four different styles of lazy loading: "There are four ways of implementing the lazy load design pattern: lazy initialization; a virtual proxy; a ghost, and a value holder."
I've used three of four.  Ghost is not the one I've missed.

Snarky: Not so fast.  I'm a lazy loader.
