Thoughts in your head are different when spoken out loud.
During the class (and exercises) I was thinking of many good ideas. And when speaking them out loud – I struggled to get the message across. Not because of the language or something like that – but because I had not thought them through.
This gave me excellent opportunity to (wrongly) feel good about myself whenever anyone said anything along the lines I had thought – making me feel that I had thought of the same thing but in a bit different wording.
