Do you believe relationships with people you have met through their jobs, and would not have met under any other circumstance, are inappropriate? Examples being; an old teacher, a doctor or nurse who has treated you in the past, or a police officer who handled a complaint you made in the past. I don't mean current working relationships. I'm unsure on my answer. If it was current teachers or doctors, then I would find them inappropriate, but as it's past i'm undecided. It still seems a little dodgy.
