A: So, what’s your favorite subject?
B: I’m interested in biology. I like studying the insects and animals.
A: Then you should take some important courses in that area.
B: I will. I don’t like history very much. I have to recite many names and it is boring.
A: I quite like history. But you should follow your heart and take more courses, just in case.
B: In case of what?
A: In case you don’t like biology later and you might be interested in other areas.
B: I see.
