Why did you choose to learn a language?
My school teaches languages and I am very happy for that because I love learning languages
To connect with my familial ethnicity considering we are only 2 generations into America and I don't know the language of my grandparents, to speak with more people here in America who speak another language and to connect with people all over the world. Also once I started learning, linguistics became very interesting.
For me it was travel.
I lived in France for a couple of years when I was young, footloose and fancy free, but I never learned French very well although my accent is pretty good for an Englishman (when I heard English tourists speak, I understood why the French can hate it so much, it's really sounds bad!). Now I travel to Italy a lot so decided to learn Italian at last. I'll probably learn French properly now, and possibly Spanish and German (my mother is Austrian).
I'm now retired, last child is nearly 18, so I can once again resume my bumming around Europe, albeit in much greater luxury!
