I wish we had a Japanese speaking cafe or something.
That would be awesome!
But I know what you mean.
Our newer classes don't have that habit as well, but the year I started in was a very small group and two of us had already learned Japanese so...
We kind of got used to talking Japanese wherever we went.
I learned the habit to the year below me (that I'm now a part of as I had too many general course failures) because I missed it too much. Now we still talk Japanese all the time.
You can do that as well with your friends... It makes for great practice!
Wow Spanish! I can't do that language... I tried but gave up nearly instantly...
