What does it mean?

I have been thinking about why I am feeling emotionally drained, and how that affects my mood. Mom came home from the hospital on Friday afternoon. She is doing better, but will still have to have tests to check how her kidneys are doing, and whether or not she will have to have weekly dialysis appointments.

On a weirder note, I was driving down the highway, when I looked at my odometer and noticed that it read 122333. I thought this was fascinating, so while at a stoplight I took a photo of it with my phone. Isn't technology wonderful?

So what could be the significance of a number sequence like 122333? Does anyone have any clue?
