Kitty: You see, my cousin Betsy is coming today with the 2.30 train, but I can't meet her at the station as I have a meeting after my lessons. Will you do me a favour and meet her?
Nelly: But I've never seen her, how could I recognize her?
Kitty: It's quite easy. She is just like her mother.
Nelly: But I've never seen her mother.
Kitty: What a pity! What shall I do then?
Nelly: Try to describe her. What does she look like?
Kitty:She is twelve, but I think she looks older as she is rather tall for her age.
