Where have you been? Ana: I was at home all the time. But I've been cleaning the house all day, so maybe I didn't hear the phone ring. Tom: Have you cleaned everything now? Ana: No, not yet. I haven't tidied up the kitchen yet. But why are you here? Tom: Don't you remember? Jane invited us to her birthday party and we haven't bought a present for her yet. Ana: Oh, that's right. Have you already found out what she wants? Tom: Well, she's been learning Spanish for a year and wants to spend her next holiday in Mexico. Maybe we could get her a guide book. Ana: That's a good idea. There is a good bookshop in the big shopping centre. I've seen some nice books about Mexico there recently.
