The Other 15%

I recently moved into a house with my roommates. It was previously owned by a family of 4, a mother, daughter, father, son kind of deal. My roommates of course took the master bedroom as their own and decided to use the downstairs bedroom as an office which of course left me with either A) the daughter's old bedroom or B) the son's old bedroom. The daughter was been in her teens and had painted her bedroom to match her drapes... which were ORANGE and MAGENTA! Well, we were planning on repainting the place anyways but I preferred the dimensions of the light blue room. It wasn't until my first night in that room that I discovered a little hidden surprise. Stuck to the top of my ceiling were these little, light green, glow-in-the-dark, star-shaped stickers. Not just one here, one there, but all over the place, like a blanket of stars above me as I tried not to think about them. As my eyes scanned up, down, side-to-side, confirming that there was an incredible amount of them, I noticed the corner by the closet didn't have them. I figure about 85% of the ceiling had them, and that one corner, that 15% of the ceiling didn't. If you're going to cover so much of the ceiling, why not cover the whole thing? Why leave 15% bare? I mean, if they ran out, don't you think they would have purchased more to complete the job? The world may never know...
