Caden and Caleb have been learning to tell time in school. So far they've mastered digital clocks, so they avoid the other and just to a room with a digital clock if they want to know the time or someone asks them.
This leads them to obsessing over the actual numbers on the clock. If they aren't all exactly the same all over the house, they're all upset about it. Our bedroom is especially difficult for them. Keith and I have alarm clocks and they rarely match.
It throws them into a panic because they don't know which clock is right and which one to believe, even though they're only minutes apart!
