Maymay has noticed that there is a large crack on her bedroom wall. This has caused us to have a daily discussion about the crack. Yup, everyday. She has measured it and remeasured it to make sure it isn't growing. She has studied it for any signs of change.
Now, a good parent would've explained how cracks happen in walls and assured their child there is no cause for concern. A really good parent might use this as a teachable moment and look up pictures on the Internet and explain house foundations, shifting and what would cause it to happen. An exceptional parent might even have their little sweetheart watch/help them make the necessary repairs and repaint the wall.
Yeah, I didn't do any of that.
I, of course, told her that it sure looks like it's a crack in the skin of the universe. Upon further inspection, I told her it simply MUST be a result of a time explosion and The Doctor will be very interested in seeing the crack in her wall. Very interested indeed. I now have Maymay excited that the crack in her wall just might actually be a crack in time, and that The Doctor might be arriving at any moment with Amy and Rory. I have promised her that should The Doctor actually arrive, we will happily go off in the tardis to explore all the wonders he has discovered.
This has had a few unexpected results. We have begun looking up at the stars at night. We're learning about constellations, stars, and galaxies. She's asked me to get us a telescope so we can better look at space and maybe catch a glimpse of the tardis. We started looking up telescopes to see what they cost, which one will suit us best, and the difference between them.
Anyway, a good parent would've explained that crack in the wall.
