A lawyer was fired after he refused to participate in a retreat his boss wanted him to go on. The boss wouldn’t tell him what was going to happen at the retreat because it was supposed to be a big secret. Fortunately, we live in the age of the internet and search engines. Here is what he probably found when he Googled up the ManKind retreat, which is apparently all over the US.
Personally, I think retreats designed to help people get in touch with themselves are largely a scam. The 70s was full of them. They were used to indoctrinate people into cults like EST and the Moonies.
