Unfortunately, I do this more often than I would like to admit. I play books on cd and know I'm totally distracted when I have to find the cd case, find the correct disc, remove the disc from the changer and insert the new disc. Then I have to put the old one away...

I'm also guilty of having my phone accessible. I think I just need to give it to my daughter when we're in the car so I don't itch for it.....
