Time & Distance change everything?

I really don't understand him any more now. We have been best friend since young but does all this friendship and understanding fade as we are now far away from each other? or does the time we have spend separately does all this? I really hope we could be like old times, for now I really don't understand what you are trying to do. Is it you or it is only me who changes after all this time we have not really spend together ever since SPM. Haiz .........
