I have two opinions on this. 1) It'd be more awezome if every person in the world started talking english and all other langues were lost, imagine how easy it would be? 2) This has nothing to do with it, but if we all were to grow different wings due to what kind of person we are(angerl wings, demon wings, bat wings, different bird wings etc) that'd be the most awezome thing ever :3
1. I like being bilingual, it makes me feel speshul ;_; So no. 2. We'd have to throw away all of our shirts, or tear them apart, since the wings wouldn't feel comfortable underneath them. So another no. And I don't wanna re-learn a language I already know, so no to the original idea of the thread.
