  Jeff: ok, good you're telling us
  Jeff: should we buy anything?
  Maria: a bottle of wine maybe?
  Jeff: red or white?
  Maria: Wait, I'll ask Marion
  Jeff: ok
  Maria: I'm just afraid she cannot drink red after the operation
  Maria: yup, she asked me to buy white
  Jeff: perfect. So we'll get some 
  Jeff: see you soon
target: Andrew and Jeff inform Maria that they'll be there in an hour. Jeff'll buy a bottle of white wine as Maria wishes.
