I took a webinar on how to write a resume and the people teaching it suggested...1) someone with a "title" (doctor, nurse, minister, teacher, CPA, police officer, etc.), 2) someone who "works for a living" (laborer, cashier, factory worker, bus driver, cook, housekeeper, etc.), and someone who "will always have nice things to say" (little old lady from church, friend of your mother, people you babysat for in high school, etc.).
When I was involved in the hiring process, I was turned off by boyfriends / girlfriends, parents of boyfriends / girlfriends, people who had their name in the county court section of the newspaper frequently, people who had been fired from the facility, etc.
