Marianne27: Hello Marc! Guess where I am standing right now!
Marc: Well, I don't know. Help me guess.
Marianne27: I am at the start of a big street. If I go straight ahead, I will reach a museum.
Marc: What is on the corner?
Marianne27: There is a market on the opposite side.
Marc: I know where you are! You are in front of my house!
