I used to take private lessons in the US on a regular basis, and ended up speaking more Spanish in the US than here. While I have to interact with people in Spanish on a daily basis, whether it's a cashier, uber driver, waiter, wife's family and friends, it is very limited and superficial, and it is almost always the other person doing most of the talking. Did other people eventually just become fully fluent after living here a few years? Or do you need to buckle down and basically go back to school?
