Reality TV is actually for Reality (which this show has none).
Tammy doesn't want to gossip about her friend that's fine. It doesn't stop them from gossiping & it doesn't mean she has to be apart of it. I don't care if Tammy is on the show or not honestly that doesn't mean she is "boring" because she doesn't want to speculate about someone's marriage. It just means this scene is not for her lol.
