  Chris: So?
  Bernie: Friday after work?
  Marty: Works for me :)
  Chris: I'll talk to my wife about it. We had some plans, but maybe we'll be able to move them.
  Bernie: What plans?
  Chris: She wanted to go to some stupid exhibition. 
  Marty: So why not let her go alone and you join us?
  Chris: That's actually date night.
  Bernie: A what then?
  Chris: A date night. Something she read about and we decided to implement...
