text: Nathalie: I've just been to the most amazing salsa lesson! You should regret ditching me :P
  Sara: Come on Nat, we didn't ditch you, I was just busy ;)
  Gabrielle: If having a flu is ditching someone, then yes, I definitely ditched you
  Mary: Tell me more about the salsa :>
  Nathalie: The teacher's amazing! She's so talented, plays great music and really can teach. Even I picked up on something - first classes!
  Mary: Sounds great, when are the classes?
  Nathalie: Twice a week, Wednesday and Saturday
  Sara: What time at Saturday?
  Nathalie: 11 - I can't wait, I'm so excited!
  Mary: I'd like to come if you're saying it's so great, but Saturday at 11 may be tricky, especially after a night out
  Gabrielle: Well, if you stay up until 6, then yes, but you don't have to ;)
target: Nathalie went to a salsa lesson which she really enjoyed. She will attend classes every Wednesday and Saturday. Her friend may join her.
