My five-year-old, Micah, displayed some interest this morning in how Mommy puts in her contacts. I let him touch one and then I put my first one in while he watched.
Me: "Look at how you can see the circle in this eye, Micah."
Micah: "Did you put those 'cracks' in there too?"
(Okay, maybe my eyes look like I need a little more sleep!)
