***** NOT A TEACHER *****
Hello, Ercantuncer:
I do not know your first language, but I am guessing that there are exceptions to the rules of your language, too. Am I right?
Well, native speakers (at least here in the United States) have no trouble using the progressive sometimes with stative verbs.
You have probably heard of McDonald's [the hamburger chain of restaurants] famous slogan: I'm lovin' [loving] it.
My books tell me that the stative -ing is often used when the idea is "MORE and MORE":
Mona: Do you still work with James?
Raul: Yes, I do.
Mona: You told me that you did not like him. He seemed so strange.
Raul: Well, actually, now that I have come to know him, I find that I am liking him a lot. (That is, with each passing day, my "liking" for him grows.)
Many of us older people might say: "There are some things that I am not understanding about today's young people." Here is what a businessman was quoted as saying: "We're understanding that we are in a tough economic environment and we have to innovate and invest." (Los Angeles Times, July 2, 2008).
