"I don't know," Caitlyn adjusted her yellow bikini top. "We aren't ready to go public yet."

"I bet," Isabella smirked.

"What's that supposed to mean?" Caitlyn shot back. She was so sick of Isabella's innuendos. Her sister always thought she was so much more knowledgeable about the world than her.

"Oh, nothing." Isabella rubbed sunscreen on her long, tan legs.

"You wouldn't understand, Bella," Caitlyn said sharply. "This is a real relationship. An adult relationship."

"Why wouldn't I understand?" snapped Isabella. "I've been having adult relationships way longer than you."

"You are so immature. You don't know what I mean. Just take my word for it. After all, I am the smarter one." Caitlyn felt bad immediately after she said those words. She didn't really feel that way; Isabella just made her so mad.

"Maybe book smarts," Isabella said in a flat tone. "But Cait, you have a lot to learn about life."

"Why do you always try to make me feel inferior to you?" Caitlyn asked.

"I can't help it if you feel like that, Cait. I am who I am."

"Yeah, you're turning into a clone of Mom," said Caitlyn. "In ten years, you'll be sucking down bottles of vodka and bitching about what you could have been."

"Shut up, Cait!" Isabella yelled, jumping off her lounge chair. "Don't ever compare me to Mom!"

"That's where you're headed. Right down the tube with Mom." She knew she shouldn't say such hurtful things to her sister. Why does Bella have to act like such a bitch sometimes? Isabella always acted like she was better than Cait, as if Caitlyn was clueless about everything in life. She was so sick of it.

"You are a bitch, Cait," Isabella said angrily. "You really are."

Caitlyn watched her storm into the house. I shouldn't have said those things. I'll give her some time to cool off then we can talk.
