Started to learn french again

I learned french in school for 1 year. My mother started to learn some greek on duolingo and she persuaded me to start learning french again. I was pretty amazed how much I still understand and speak since then, because it has been 20 years already when I learned french at school and only for 1 year. I hope I have enough perseverance to learn for some time so I can improove my french skills. But the app is quite nice and it makes fun seeing my progress.
