Lesser Maintenance

Over at my MIL's house, they have window blinds since it's more convenient over at their place. Of course, they also have lots of curtains, specially in their living room. The window blinds are located inside their guest rooms and I really don't know why. I guess it's because their guest rooms are almost always close, so having the blinds there is much easier to maintain the cleanliness; the curtain would gather more dust, I think. :)
