“You don’t have to be amphibian to hydrate through your skin.”

“Get under the umbrella!”

Jess had a theory about everything, but her ideas changed from day to day. It was hard for Emily to remember whether her sister was primarily feminist or environmentalist, vegan or vegetarian. Did she eat fish, or nothing with a face? Uncertain, Emily let Jess choose the restaurant when they went out to dinner.

The two of them nibbled samosas at Udupi Palace, and Emily said, “I’m sorry I kept rescheduling.”

“That’s okay.” It was two weeks past Jess’s twenty-third birthday, and the restaurant with its paper place mats looked small and plain for a palace, but Jess didn’t mind.

“Veritech has been insane,” Emily explained, “and Jonathan was here….”

“Oh, Jonathan was here,” Jess echoed in a teasing voice. “What did you do with Jonathan?” She often took this tone about Emily’s boyfriend. The longer the relationship went on, the more serious it seemed, the more she teased. Jess didn’t like him.

“He was just here very briefly on his way to L.A.,” Emily said. “The last couple of weeks have been—”

Jess interrupted, “I’ve been insane too.”

“Really?” Emily realized she sounded too surprised and added, “Doing what?”

“I’m taking the Berkeley, Locke, Hume seminar, and logic, and philosophy of language….” Jess paused to sip her mango lassi. “And working and leafleting.”

“Again?”

“For Save the Trees. And I’m also taking Latin. I think I might be as busy as you.”

Emily laughed. “No.” She was five years older and five times busier. While Jess studied philosophy at Cal, Emily was CEO of a major data-storage start-up.

“We’re filing,” Emily explained.

“I know,” Jess said in a long-suffering voice.

Jess was the only person in the world bored by the IPO, and Emily loved that about her. “I got you a present.”
