I have always told people that I was the super baby in my family. Based on their follow-up comments, everyone has understood that this meant that I was significantly younger than my siblings. Of course, I’d never said it to a French person in French.
Turns out, they take things literally as the person I was speaking with thought I was suggesting that I had been enhanced in some way, like genetically or perhaps radioactively. I got really depressed after she said that because I realized how awesome it would be if I actually had been a mutant instead of just a lame normal human.
The French really know how to bring the fun level down.
