That's precisely wrong. No rebellion involved. Languages are hard. If you learn two languages, you'll be half as fluent in either language.
LOL! My 23 year old daughter, speaks English, Spanish and French and is fluent in all. She has lived for a time, in both France and Spain. My French ancestor who came to America in the 1700s, refused to teach his children French and insisted that they speak English, although he helped his fellow militiamen during the Revolutionary War by speaking to French troops and getting supplies for their fight against the British in 1781.
“Languages are hard. If you learn two languages, you’ll be half as fluent in either language.”
Americans are lazy about languages, so it may seem they are hard.
Most people in Europe are very fluent in two languages, at least.
And most offspring of immigrants that I know of, speak their parents language passably.
Back 100 years ago, immigrants wanted to “anglicize” as fast as possible, and distance themselves from the foreign identification.
Today it is cool, to have a foreign identity.
No. Not at all. My husband grew up speaking four fluently, and two more passably.
Once you have mastered two, the third and subsequent usually come pretty easily if you’re young.
I have only English and Spanish. Working on Mandarin slowly and wish I’d started much earlier.
