Yeah I'm the same as you !
You know if I had to learn english only by my teachers my englis would
suck DX
I'm a yaoi addict you know and in internet, there's sot a lot of stuff in french
because yaoi is a world wide thing, see ? And so almost everythy fic, fanart or comments were
written in english so I didn't have the choice I had to be good in english XD
Plus, I leared the language by learning every lyrics of the songs that are on my ipod : 643 XD
YAY !! We can totally be friends
PS
yes depending on the time you use
yes that sentence is perfectly correct, you can use it about a place, an event, a person or even a language if the sentence is :
je connais cette langue !
Really ? Well I'm currently trying to learn the American anthem XD
