>>86605221My dad speaks finnish like 6 times a year at most and got a stroke that hit the language part of his brain so he had to relearn* his second language where we live now and he still can speak finnish with like zero problems
This made me extremely skeptical to people losing their first language
*he spoke essentially like a small child, like the tv was called "electronic thing", tv remote "electronic thing", computer "electronic thing" etc so very limited vocab
