So give yourself a pat on the back for working on it as hard as you did.

Is this in a puzzle book, or how did you find it?

I had a friend give it to me, that also couldn't figure it out.

Do you want an explanation?

Yes Please.

You promise me it's not homework?

Yes, I promise, its driving me crazy!

Here's a sort of helpful answer on how to figure it out --

Einstein`s Riddle:
Einstein wrote the following riddle. He said that 98% of the world could not solve it. But several NIEHS scientists were able to solve it, and they said its not all that hard if you pay attention and are very patient. Give it a try:

There are 5 houses in 5 different colors in a row. In each house lives a person with a different nationality. The 5 owners drink a certain type of beverage, smoke a certain brand of cigar, and keep a certain pet. No owners have the same pet, smoke the same brand of cigar, or drink the same beverage. Other facts:
1. The Brit lives in the red house.
2. The Swede keeps dogs as pets.
3. The Dane drinks tea.
4. The green house is on the immediate left of the white house.
5. The green house`s owner drinks coffee.
6. The owner who smokes Pall Mall rears birds.
7. The owner of the yellow house smokes Dunhill.
8. The owner living in the center house drinks milk.
9. The Norwegian lives in the first house.
10. The owner who smokes Blends lives next to the one who keeps cats.
11. The owner who keeps the horse lives next to the one who smokes Dunhill.
12. The owner who smokes Bluemasters drinks beer.
13. The German smokes Prince.
14. The Norwegian lives next to the blue house.
15. The owner who smokes Blends lives next to the one who drinks water.

The suggested steps to the final answer below are not unique and are just one of several logical approachesthat one could take to reach the proper solution. First consider color. The Norwegian lives in the first house (Fact 9), which is next to the blue house (fact 14). Thus, the second house is blue. The green house is to the left of the white house (Fact 4), which means that the green house must be either the third or fourth house. Bu t the green house cannot be the third (center) house, because the owner of the center house drinks milk (Fact 8) and the owner of the green house drinks coffee (Fact 5). Thus, the fourth house is green and the fifth house is white. Since the Norwegian lives in the first house (Fact 9), and the Brit lives in the red house (Fact 1), the first house must be yellow, leaving the middle house red. Next consider drinks. The owner of the red (third) house is a Brit (Fact 1) who drinks milk (Fact 8). The owner of the green (fourth) house drinks coffee (Fact 5). The Norwegian lives in the yellow (first) house. The Dane drinks tea (Fact 3), and must be the owner of either the blue or white house. But he can't be the owner of the white house. If he were, then the beer-drinking Bluemaster smoker (Fact 12) would have to live in the blue house, making the Norwegian in the yellow house drink water. But that can't be right because........... the water drinker lives next to the owner who sm okes Blends, not Bluemaster. Thus, the Dane must live in the blue house, and since the beer-drinking, Bluemasters smoker cannot live in the yellow house (because that owner smokes Dunhill), he must live in the white house, leaving the Norwegian in the yellow house drinking water. Next consider nationality. Only the German and Swede are unaccounted for. The German smokes Prince (Fact 13) and thus must live in the green house, since the owner of the white house smokes Bluemaster. Thus, the Swede must live in the white house. What about cigars? Only Blends and Pall Mall are unaccounted for.
