What do the girls have in common?

M: Jane, I would like to introduce you to my sister, Ellen.
W: Glad to meet you, Ellen. Bob tells me that you are interested in African art too. In fact, he says that you plan to spend the summer in Zimbabwe.

M: I’d like to drive to the concert, but my brother has the car tonight.
W: Who needs a car? We can take the subway if we go a little earlier.
