I think anyone who says they’ve never lied is lying, LOL. And clients lie a lot.
Sometimes, it’s too early in the training relationship to reveal the complete truth. Details about me come out as trust develops. I haven’t lied about major stuff like, “Do you have a life-threatening condition that might affect my ability to train you today?” It’s been more along the lines of my “whys” for my less desirable behaviors or lack of better behaviors. In that case, I’ve given partial truth.
I think our clients are like that, too. They will tell us what they think is relevant, what they’re willing to reveal, based on how much they trust us, how much time we have together, and how well the training is going. If we are a good training team (trainer and client – both have to invest in the relationship), the bud opens up slowly and we are able to see more and more petals of the flower.
