text: Kevin: Hey guys! I need your advice about buying vs renting in London. I want to rent a flat to save up money for a better house. 
  Martha: renting is expensive in London so you won’t save that much money
  Kevin: but the wages are higher  :)
  Greg: the cost of living is higher too
  Kevin: would you go for buying then?
  Greg: you don’t really know the place. What if you don’t like it?
  Kevin: that’s a good point!
  Martha: i’d go for renting but wouldn't expect to save up a lot
  Greg: yeah, then go for buying
  Kevin: cheers guys!
target: Kevin is going to rent a flat in London first and then go for buying on Greg and Martha's recommendation.
