INVISIBILITY 

If I could be invisible for one day I would help people the police. I would help them by following suspects without them knowing. Or I would would help kids with bullies at school. Adults with there job or help stop a crime before it happens. I would help elderly do chores around their homes. 

Also I would help families in distress with any problem like money or a abusive wife or husband. I would help find lost children or animals. I would nurture animals that are struggling to live.
