Garages with windows

So, ever notice how some folks build houses where from the front it simply looks like a symmetrical house with a wing on each side of a larger main section? Then when you go around back, one of those wings is really a garage with the other being living space. A pet peeve of mine is when people don't put window treatments on the garage windows. From the front it becomes obvious that it really isn't the living space it's supposed to look like because every window in the house except the garage has window treatments.

Let's get real here. If you want it to look like the rest of the house, finish the deal! If you don't care that it looks like a garage, well, you wouldn't have built it that way to begin with, would you?
