Hmmm, all of mine did.
All of my immigrant ancestors did assimilate here.

Sure, back in the day......but you don’t see that now. One trip to Miami Florida will tell you that.

Lately every time I go to Walmart half the people in there are speaking some language other than English......and that includes the employees.
“Press one for English, 2 for Spanish”......that’s bullshit....speak the primary language.
