I am very jealous of you that you learned another European language so well.
I am somewhat OK with Spanish now and my French is very rusty.
I will make sure that my kids speak ATLEAST two other european languages fluently and one Asian language by the time they are 18
Today, the more languages you know the more successful you are.
As the old joke goes:
What do you call a guy who speaks THREE languages..... TRI-Lingual
What do you call a guy who speaks TWO languages.. .BI-lingual
What do you call a guy who speaks ONE language....
.....
....
American!
The joke is on us.. we need to learn more languages like German, French, Spanish, Portuguese, Mandarin, Hindi etc.
Latin - it is the root language of many. Send your kids to catholic school, make sure they take latin.
The rest is easy.
Except spelling - I can’t spell in six languages. In fact, I can’t spell in any of them. Heh, Bier, beer, cervesa, ....
