I am sometimes asked “do you say bad things in a reading”? Sometimes I have to talk about difficult things like loss or hardship so in that sense, yes. Some people are under the assumption that readers have restrictions. Although many of the readers that I know (myself included) do have ethical boundaries, not all do. There are no enforced guidelines for readers as far as I know.
In my practice though there is a standard that I follow, what I receive is always information that can be used constructively. I don’t leave people in worse shape than I found them. At the same time I might not always say what a person wants to hear. Sometimes people say “you never said anything about trips”. To which I sometimes have to say that didn’t seem to be an issue, I then ask “why are you planning one”? and often the answer is no.
I remember when I was beginning my career and working in an establishment where there were other readers it was suggested that we follow a certain format of what people wanted to hear, trips, romance, lucky numbers etc. I asked “but what if that is not the reality of things”, and got a blank stare.
