My friend Andy lives in the city of Sejong, which is near Daejeon. I meet him about once a year and he is also very interested in the Korean language and Korean education. He also speaks Korean fluently and has been learning the language for a very long time.
When I was first learning Korean, and even recently, I've felt shy or nervous to speak Korean around other people who aren't native Korean speakers, in fear of being judged for making any mistakes or because I was worried it would look like I was "showing off" by speaking Korean better than them. When I met with Andy we talked about this, as well as how to deal with those sort of feelings, and what situations it would be completely normal to speak in Korean with other non-native Korean speakers. Andy had some great insight and I'll definitely be meeting with him again next summer.
