answer: #Person2# thinks time seems to crawl when people have nothing to do but time flies when people are busy with work. #Person1# agrees.
documents: #Person1#: It was exactly two years ago that we moved to this town. You started working on your degree, and I started working down at the lab.
  #Person2#: It seems like only yesterday. I suppose that I am so busy that I don't even notice how time passes.
  #Person1#: I'd expect the opposite. I mean, the way you've been studying, working on experiments and writting dozens of papers. It might seem more like four years than two.
  #Person2#: Haven't you ever noticed how time seems to crawl when you have nothing to do? But how time flies when you are busy with what you really like to do?
  #Person1#: That's true. Those days when there was not much to do at the lab didn't ever seem to end.
  #Person2#: Just wait a little longer. As soon as I finish my degree, we'll open our own chemistry lab.
