Difference in driving

Two brothers were talking. One said, "I am fed up with living in Birmingham, U.S.A. because I have to drive all the time. Why don't we move to London?" His brother replied, "But that would mean that I would have to drive all the time." Any explanation logically convincing for the above conversation?


Answer:

The two brothers are siamese twins and since the rules of driving the cars in U.S.A and London differ in the sense that in the former, one has to keep right whereas in the latter one must keep left while driving. Hence these rules perforce the twin to change for the other to drive when shifting to London.
