My suspicion about my therapists has always been that they knew a lot more about me than I actually revealed long before I revealed it. Maybe not details, but they were very much in the ballpark. We aren't as mysterious as we think. We tend to wear our issues on our sleeve in therapy. Maybe we haven't actually talked about it, but it is sitting right there pretty much in plain view to our therapists and they are just waiting patiently until we are ready to look at it.
