hello! long time no see? hehe..

i was very busy because i had to write 2 documents. it need 2 pieces of A4 sheet.
i have to write them every week because of my seminar. i hate it.X((

in my university, there are some exchange students. i and they take a same class. So fortunately, i have an opportunity to communicate with them. but,,,, we talk about serious topic for debate. i would like to talk them more and more. but my english is so poor and i take a few minutes to think how i can say what i want to say in English before speaking. they don't wait for me. when i think how i can say, they always says "it's OK!" and then go to next. i really feel frustrated. i really want to speak english well. how should i do for that?
