"Hahahahahaha...", she burst out in unreserved laughter as a joke led on to another. It was another one of those times when jokes roll on and everyone's all cracked up. It was so funny that she forgot how they even got on the topic. Then it enveloped her. Like a dark cloud engulfing the burning sun, gloom washed over all traces of happiness. She stopped dead in her laughter. But a split second later, she realized she couldn't just change temperament like some bipolar maniac. So she stretched her lips out wide and continued laughing a little more.
She rested. That was tiring. She sat down and wondered how long she could hold this up. The right way to respond is to be forward-looking and positive. But why does guilt come over her whenever she's having a good time? It almost feels like she doesn't have the right to feel happy. She wished some things could be changed but there was nothing that could be helped.
So she hung around until it was time to go home.
