Cardassians enjoyed debate and conversation in general. Cardassian meal time was as much about discussion as it was about eating. They would speak at length about a topic to show their knowledge, avoid saying something incriminating, or to obtain some piece of information from the person they were speaking to. Such was their love of conversation that it played a major role in their courtship. Courtship among Cardassians may include of bitter, ferocious arguing, a fact not remembered by the confrontational Miles O’Brien, who engaged in repeated disputes with his female Cardassian co-worker Gilora Rejal, only to be shocked when it led to her becoming infatuated with him. Pressing the palm of one’s hand to another’s palm was the equivalent of a kiss on the cheek, as demonstrated by Elim Garak and Tora Ziyal.
