I am lucky, I grew up in an Spanish speaking country, moved to the US about 30 years ago and learn to speak English, now I am bilingual, I have made a point of making sure my girls speak both languages. They understand Spanish perfectly and speak it when they have too. I also made sure that they took Spanish in HS.
Now my oldest works for a doctor's office where she uses her language skills when need it. My youngest is a Senior in HS this year, and wants to go to College and study to become a teacher, she also has decided that she will take a second major in Spanish, and have her practice for both degrees back "Home", her uncle owns an school and she can have her teaching practice down there and since is an Spanish speaking country she will have her practice too.
