the language game

I was find hard time to talk this days. I am sucks at English. My every classmates sound professional but I am wonder why they claim to be having difficulty. I am mean, during English periods, they somewhat complains that it's hard. English is hard but of course people who speaks English as main have the upper hand.

Come to think of it, I was also has hard time during my Filipino subject back in the Philippines. So why again? Is it hard to study the own language?
