to lead someone a merry dance
dolores: is it true that kylie and faisal have finally got engaged?
keiko: i know they've been together for some time, but i don't think so.
dolores: it wouldn't be the first time that they were going to and then didn't.
keiko: i think it's kylie. she can't seem to make up her mind.
dolores: she never could. always blowing hot and cold.
keiko: yes. i feel sorry for faisal. she's been leading him a merry dance.
