Who's male and female, and why? Each time A works with B, when A feels tired,and usually says, “Let’s get something to drink,” or “Let’s have a cup of coffee”, which actually means A wants to have a rest, however, B usually responds like this, “ Go ahead for yourself, I will go on with the work.” But whenever A passes this same message to C, another colleague, A always could get the answer like this, “OK, let’s have rest,” or “ I also feel tired.” and so on.
