When my husband told me the whole exterior of our house would one day be white, I cringed, not because it's not a TARDIS (I'm not that neurotic), but because white on white is boring. So as a compromise he said we could have a colored door. So I said I wanted a blue one. And honestly I wasn't even thinking about the TARDIS, I just kinda like blue.
My husband doesn't believe me. He keeps teasing me about my TARDIS door. And really, now that I think of it, I DO want to live in the TARDIS, so why not?
