Doing Experiments in a Lab

Calvin, are you free this evening?

Tom Hanks' new movie is out!

Oh, I'm sorry, Ruby.

I really want to go with you, but I have a test tomorrow.

So I have to study tonight.

OK, how about this weekend?

Um... this weekend, I have to stay in the lab to do experiments.

We are working on a new project.

I just can't believe it, Calvin.

You spent even more time in the lab than with your friends.

I'm sorry, Ruby. Maybe next time.

Oh Calvin, you have said that at least a hundred times.

You know all work and no play makes Jack a dull boy.
