Productive.

Part of my house, along one wall, used to be a sun room.
Perhaps.
I say this because the roof and wall along that length, are 90% glass, and 10% Plastic (The plastic is around because there's a sliding glass door in this particular wall of glass).
The roof is vaulted there, and comes in at what must be a 45 degree angle.
I've guessed it's a 45 degree angle, because sometimes I stand in the sliding glass door, that is part of this glass wall, and have a cigarette (rather than out on your delicious patio- due to unpleasant weather, or fear of rats).
And, when I have a cigarette and look STRAIGHT up, I can see exactly right behind me.

Now what's neat- is what's behind me is a wall of mirror.
Not a wall-mirror, or a mirror on a wall- but a wall that is made of 100% mirror, and no anything-else at all. I presume it was put in place to make the little suite my room mate and I share seem less cozy, and more spacious- like the shelves of vegetables in supermarkets.
This mirror wall behind me is what I see when I look STRAIGHT up, into the vaulted ex-sun room, roof shaped, ceiling bit.



So, when I look up, I see what's ahead of me.
