What I mean is that I am doing language exchange where I am trying to practice English and help people in French, but I sometimes find myself doing a bunch of things in French after my exchange sessions, because when I interact with people they tell me about a movie that they watched, a song that they listned to, youtube channel that they liked, a lesson that they enjoyed ... EVEN a grammar rule that they don't understand well and so on and so on ... I think then I'm not practicing only English, I'm practicing French too ...
My English improves. I find people (partners) with whom I have too many interesting things to discuss. That is absulutely great, I think people are much better than langauges:) As our levels in our respective langauges aren't so high, we discuss things in English.
I also read materials about langauges I'm interested in written in other langauges.
It would of course also be great if my target langauges improved as well:) Particluraly because it is langauges of my freinds and it is better to communicate with your friends in each other's native languages.
But well, they would if I were not so lazy.
