Jordan recalls the time in 1917 when she saw Gatsby and Daisy together. From Jordan's description do you think Daisy was genuinely interested in Gatsby?

From Jordan's description, we can easily infer that Daisy was just as interested in Gatsby, as Gatsby was interested in her.

When I came opposite her house that morning her white roadster was beside the curb, and she was sitting in it with a lieutenant I had never seen before. They were so engrossed in each other that she didn’t see me until I was five feet away.
