I could have thrived with this superpower for secret santa gift exchanges in middle school. Been the champion of hide- and-seek games at play dates. Nowadays, it’d be handy if I was a spy or had enemies that were out to get me like Harry Potter did.
With invisibility, I would have boundless information that I could listen to from others. I could eavesdrop more directly when I hear an interesting conversation in a park. I would start to really become a good listener. Sneaking into concerts would be so fun. Boundless VIP passes. There would be no need to find a third door entrance.
Being more internally extroverted myself, with invisibility, I could see more of an introvert lifestyle. Not that more shy people are not seen but because they are not heard, sometimes they are overlooked. This strength of listening can truly be embraced without feeling the obligation to contribute.
