My partner's family all speak Russian, which is not my native language. I used to be in classes which helped me have regular practice at listening, but now that they are done, I'm finding myself in embarrassing situations with the family where I mistake one word for another (confusing "как грибы?" for "как рыбы?", and saying they are good when I clearly have no mushrooms on my plate), or they will ask me questions and I didn't even understand one word. When everybody is speaking Russian I just stay silent now so I don't make a fool of myself, but this is getting to be a big problem.
Reading is a lot easier for me since I can go at my own pace, look back at parts that I don't understand, and skim for context. All of this is impossible in conversation, but I don't want to be mute around them forever. How can I improve my listening? Most movies and TV shows are difficult for me because they speak so quickly, but maybe there are some good ones for children that aren't boring?
