Why do people from the Middle East not care about the appearance of their houses?

Lot's of Us and Uk people don't take care of their house appearance either !!….have you seen their smelly greasy houses, they never wash the carpets, the walls are greasy full of stains, the pots never rinsed and the smell of cat's hair are intense and horrible !!….

Go build up some gut and talk to them. The longer you let this happen, the more you will assume a neighborhood price drop. Sooner or later this will become a prejudice and race issue for you.

Not everyone knows that a properly kept house and lawn is a responsibility especially if they are just coming out of large cities or other countries. I believe this lawn and house appearance thing is more of an American attitude. Since they are minorities, perhaps, you can help them make themselves comfortable by telling them how everyone in the neighborhood takes a nice kept house as a responsibility. Expect dirty looks and negative attitude but look beyond that and try to be helpful. After this you may even become friends.
