qqp question1: "Is it ""I am on the bus"" or ""I am in the bus""? I read it somewhere that if a moving object is at still then it is ""in"" otherwise it is ""on"" which is to be used. If that is true, then can I assume, that the moving object is at still if ""in"" is used in a sentence?" question2: I always see people writing the same sentence twice, as if to stress a point; e.g. Am I right? Or Am I right? What really is its use?
