Who are the two speakers?

W: Hello, Bob. I haven’t seen you for a long time. How are you getting along with your preparations for the entrance exam?
M: Well, I really can’t tell. Anyhow, I’m doing my best, working night and day.
W: So am I. Sometimes, I feel very tired, both physically and mentally.
M: I feel the same. I often suffer from headaches and general weakness. Not enough time for sleeping. I don’t know what will become of me if it goes on like this for long.
W: And no time for sports, even music, not to mention films or TV programs.  All we can see is exercises, exam papers and this sort of things.
M: It seems that to go to college is the only future we have.
W: Certainly not. Even if we can’t go to college, we can take up many other jobs and do our bits for the society as well.
M: Quite right. But we’ll get more knowledge after studying several years at college. That means we can work better for our country and people after graduation.  In addition our parents lay great hope on us, and we shouldn’t make them feel disappointed.
