hi,tarak.
i have answered some of this question in Noor's ,
here i will say
Yes .
your asks are very good!
i am not talk with the native at first,
i have a good partnter ( my countryman,we study together,everytime we all had trouble to express,then we said ,we would look for it,in fact not always did,but when the next time we mentioned the trouble ,we both remembered again,
so when could find the answer naturally,
and won't forget .have a good partner is big wealth)
I like watch movie.
I saw mang movies,i like to guess the country and the plot of the movie.
i think when you want to know why,you have to find their root:Their culture,religion, loving sometimes.
