It’s an interesting conundrum in many ways. Something like quantum mechanics that you observing the situation and commenting on it changes this world. Talking about feelings that might be in the future change the fundamental nature of how things are working.
In some ways you can say it’s tipping your hand. But isn’t that the same as communicating what you want in the first place? Are you secretly working to what you want anyway?
