I've been learning German since high school, because I always wanted to learn a second language. I started with German because my older cousin took German.
I started learning Toki Pona a couple years ago, because it's the simplest constructed language, and it seems to have a great online community. I've fallen off the wagon a bit on that, and I need to get back on.
More recently, I've starting to learn Korean. My husband asked me to teach him German, and it inspired me to try something new myself. I wanted to learn a language with a different alphabet, and I loved the style of the Korean alphabet. Plus, music helps me learn, and there's tons of k-pop. I've seen some really good South Korean movies, and this gives me a reason to seek out more of them. Yes, I'm aware Korean is one of the hardest languages for English speakers to learn. I have the rest of my life to try.
