Here I go... again.

I like learning new languages because it can open a completely new world. You can meet very interesting people from differents places, and understand different cultures and points of view.
My English is really rusty. I don't practice much because I am also trying to learn another two languages at the same time. I dont have the time at the moment, but in the future I would like to meet new people for language exchange

Although your English is a little rusty, it will come back to you quickly once you get into it again.

Good luck mate.
