Make yourself at home.
Thoughtful. Colorful. Spirited. Engaged, and Entertaining!.
Mean. Argumentative. Abusive. Profane, or BORING!.
Or, as more eloquently stated by The Bard of Avon...
Conversation should be pleasant without scurrility, witty without affectation, free without indecency, learned without conceitedness, novel without falsehood.
