Kiss better.
There was an exclamation and clatter in the kitchen. Nyota ran to the door and saw Spock with his hand in the cooling unit.
"Spock? Are you alright?" asked Nyota.
"A minor burn," stated Spock.
"Nyota stepped toward him and gently lifted his hand. She could see the faint mark of the burn on the back of his hand. She lifted his hand to her lips and kissed it. His eyebrow rose.
"Kissing it better," said Nyota and almost laughed at his expression.
"A highly illogical action," stated Spock frowning slightly.
"Nonetheless common amongst humans, in the case of minor or superficial injury, especially when an element of emotional comfort is warranted." said Nyota.
"Kissing an injury risks introducing bacteria and other contaminants and in the case of a burn, warms the injured area. Illogical and counterproductive" stated Spock inserting his hand back into the cooling unit.
"The purpose is to make the kissee feel better; feel cared for," stated Nyota. "Do you feel cared for?" she asked teasing knowing full well that this was an impossible question for him to answer.
Spock was frowning slightly, not in displeasure but in the way he did when thinking deeply. "I believe my mother may have done this when I was a child," he said thinking aloud.
