Study a new language… Why not?
I belong to a group of people who love languages; in fact, I’m curious and try to learn at least the basics (and my husband thinks I’m crazy!) But, yes, that’s what I like. Well, more than just learning them, I’m curious about how “they work”. Have you ever tried Duolingo or Memrise? I did! And there is a lot of apps and websites where you can practically learn any language, if not for free, for a low price.
