You have a secret superpower: the ability to appear and disappear at will.
When and where will you use this new superpower?
Tell us a story.
And this is my response:
I would use this secret invisibility superpower when I do not want to be seen which is usually when I am outside or in public or around certain people, and then I could walk around and enjoy the outdoors more and I could explore various places outside and inside that I normally would not visit or that I would not normally get to enjoy comfortably .
