Please Don't Do It.
You could find me unpleasant but I want to ask you a favor:pleasure, if you want to improve your English don't ask to me;, I don't know it;, I'm still learning.
I can't learn it if not native English speakers writes to me: "How r u?". I have to know spoken and, above of all, written English. Of course I can talk with not non-natives people but that who speak fluent English.
I tried to learn with beginners people like me but the results are that I'm more confused than before now. No one wrote to me to improve his Spanish and, although I know it better than English, I can't help in Spanish, I'm not ready.
Little exercise:
If I touch a flame, I get a burn.
If I get up early, I'll go to the gym.
If I knew English very well, I would talk with everyone.
If I had known English very well, I would have been the master of the world.
