Are you jealous?

  Question N1: At a party or reception, you are in a good mood and suddenly you notice that your companion has stopped paying attention to you and is flirting with the host (hostess) without slightest remorse. You reaction?

Choose answer:
I'll pretend that nothing's happened and won't say anything after that
Oh, yeah?! Well, I can take revenge. I'll be flirting with the hostess (host) all the evening and spoil the party.
I'll make a row and sort out our relationship at public, and then will slam the door, leaving.
