If I had any power, I would be invisible because then I could do whatever I wanted, like explore a stranger’s house or go on a cruise without paying.
Either that or stopping time because I could also do as I pleased and there is nobody to stop me. A kidnapper could be crawling into our bathroom window and when I stop time he would be still and I could push him out and give him a good bruise and he couldn’t hurt me! Then I would put bars on the window and resume time (I got the bars at the store when everybody is paused). That would be cool!
Those are my two favorite powers.
