Languages should be learned at a young age....not in HS. We do things ass-backwards here. Some well to do parents send their young kids to private language schools but most Americans take on languages in HS. I had two years of latin in HS...and then 2 of Spanish. The latin was useless even though I enjoyed reading stories about Caecilius in latin...
Yeh... going to make sure when have kids they are like tri-lingual by 5-6.
Not exactly hard to do, especially as odds are that partner will be foreign.
If end up staying with current GF then will:
Have me only speaking English to them.
Have her only speaking Portuguese to them.
Having GFs Mum only speaking Arabic to them. (might not be enough to be fluent... but will at least understand a lot like GF does.)
Then if speak fluent Portuguese Spanish can pretty much be picked up without that much hassle.
GF could:
Speak fluent Portuguese and English, speak okay Spanish and understand a lot of Arabic... by the time she was 7-8 years old. As a result of a pretty similar method.
