There's a tv show on where Julia Dimon travels to Bogotá Columbia and during this episode she says that the super power she would most like to have is language. I agree! I would love to know any language that is needed to communicate whereever I am in, and in whatever country!
Before I was five, I spoke Dutch fluently and then lost most of it when I learned English. Luckily I can still understand a lot of it! I took the obligatory French in elementary and high school and even a little bit in college. High school offered German and Latin so I took those too. Looking back, its too bad they didn't offer Spanish - "dos cervesa por favor" will only take you so far!
What super power would YOU like to have?
