What feelings does Jonas experince when he is given the holiday memory in The Giver?

This emotion is love.  When Jonas experiences the memory
of grandparents, he realizes that there is an emotion in the room that he has not
experienced before.  He is perplexed.  Jonas has never experienced love, because it does
not exist in the community.  This occurs in chapter 16, page 123, when The Giver shares
his favorite memory.

When The Giver asks Jonas what he is
feeling, Jonas is uncertain:

“Warmth,” Jonas replied, “and happiness.  And—let
me think.  Family.  That it was a celebration of some sort, a
holiday.  And something else—I can’t quite get the word for
it.”

And on page
125:

Jonas
hesitated.  “I certainly liked the memory, though.  I can see why it’s your favorite.  I
couldn’t quite get the word for the whole feeling of it, the feeling that was so strong
in that room.”

“Love,” The Giver told
him.

Jonas repeated it.  “Love.”  It was a word and concept
new to him.

Jonas considers
the impracticality of grandparents, but still likes the idea of love.  On page
126:

“I liked
the feeling of love,” he
confessed.

Jonas states that
the memory shows a dangerous way to live. He says he is talking about the candle and the
fire, but he is really talking about love.  Love is dangerous because it leads to
attachment.  Attachment makes control difficult.  There is no attachment in the
community, and control is considered most important.
