Ah! I understand! Sadly, for me, I do think that languages start to deteriorate if I don’t use them… but very slowly. I’m unfortunately not someone who likes to watch movies or TV shows too often, so it’s very easy for any given language to fall out of use for me (even passive use, i.e., listening). That’s awesome about your job interview! I’m sure the trilingual code-switching impressed them. I hope it went well and that you find yourself in a job you love very soon!
