Spending Wisely

Jamie was trying to explain to Gisèle was "spending wisely" meant.  She thought she had a grasp on the concept, so decided to give him an example.

Gisèle, smiling:  "So, like, what if I had $100, and I bought 100 scoops of ice cream?  What would you say?"

Jamie:  "I would say that you did not spend your money wisely."

Gisèle:  "So, then, what if I had $100, and I went to the shoe store, and I bought a pair of polka-dot high heels?  And then I had $4 left, so I went to the clothing store and I bought some underpants, and then I had $1 left, and then I bought a Rapunzel car kit?"
