Being invisible forever? Tough thought, but I'm prone to take the gift if it were offered - of course only if I won't lose my ability of moving things and getting noticed by other senses than view. It would mean a different life with different risks and chances and I'm interested in the experiment.
I'd have to take careful precautions against getting caught by dangerous characters. It would be wise to abstain from eating garlic, for instance.
The three stars are for permanent invisibility. Having the gift of being invisible at will would be GREAT.
