What were differences between Receiver's house and others in the community? What 3 memories did he receive that he has never experienced?In Chapter...

One difference is that the Giver's house is furnished more luxuriously than the other homes of the community. The other homes have furniture that is strictly utilitarian, with no decorative elements. In the Giver's home,

The fabrics on the upholstered chairs and sofa were slightly thicker and more luxurious, the table legs ....were slender and curved, with a small carved decoration at the foot (74).  

The most important difference is that the Giver's home has walls covered with books.  In the other homes of the community, there were reference books and the book of the rules of the community, in other words, only books that had some practical use, nothing like novels or poetry. 

What purpose did these differences serve for the Giver? Did the community simply want him to be more comfortable and be able to pass his time reading, or was there some more important reason for this difference? 

The three memories Jonas receives in Chapter 11 are sledding in the snow, sunshine, and sunburn.  Notice that the Giver begins with two pleasant memories and then a more painful one.  Why did he choose to present these memories in this order?
