answer: #Person1# and Susanna are looking at a photo taken on the day before Ricky's birthday and recall the past.
documents: #Person1#: Susanna, look at this photo. It is near a cliff, but I don't remember where we took it.
  #Person2#: Um, well, it still looks cold. I think we'd been for a cycling to the Red Mountains National Park.
  #Person1#: Oh, I remember there was a cafe at the top of the cliff. We went there to have a rest and took a picture of the view.
  #Person2#: Yes, it's kind of dangerous. There is no fence, so we have to be careful.
  #Person1#: It is really a good picture.
  #Person2#: Oh look, there is a date on the back. We took it on August fifteenth.
  #Person1#: Yeah, it is just the day before Ricky's birthday.
  #Person2#: Oh yes, yes, we celebrated it together at Ricky's new house.
