Learning different languages

I wish I could speak many languages. If it was possible then I could travel all around the world and always be able to communicate with people all around the world. It would also be very interesting to understand what people says to each other on buses and in restaurants etc. When people speaks their native languages it is not understandable by me. Moreover, I imagine that they are discussing very important matters like peace on earth or how we can resolve the issue of global warming.But, it is also possible that they are just talking about what we will take dinner.

to learn a language (Learning Languages sounds better but this works too)

But maybe they just talk about what to have for dinner.
