Rather than getting on a party line, why not try dialing direct?
"Rose here, requesting my primary spirit guide for a consultation. Would my primary spirit guide, aligned with truth and love
(what? no Power? -- angela) and acting in the interest of the highest good for me and for the world, please check in with me now?"
When someone picks up, ask, "Hi, who are you, please, and what are you interested in?"
Enough with the yes or no questions -- it's just too Ouija.
