Who? Nick Carraway & Jay Gatsby Where? Their apartment When? Thursday after sunset. What? Pesach פֶּסַח Status? Incomplete, closed. Rating? Probably low.
Nick was not Jewish. Nor had he spent any considerable time with anyone Jewish. But he knew Gatsby was, and though he hadn't known him long enough to know if he was a practising Jew, Nick didn't see why he shouldn't make some effort to focus on his friend's religion, in case he thought no one cared. And Nick was determined that Gatsby didn't feel that way.
He had used the Google on the computer machines to find out what was required for a Passover Seder and really, it wasn't entirely easy to come by. He had spent a frustrating morning looking for a lamb bone and had had to compromise on chicken. Three baked eggs all failed, so he had hard boiled one. And bitter herbs were difficult to come by as well, which meant he had gone for a lettuce and a radish and hoped that God would forgive him and appreciate the intention.
The wine he could do, at least even if everything else was makeshift and not perfect and genuinely a hideous mess, he had the wine.
He used the hour or so Gatsby was out on business to throw everything together, eyeing the finished table rather sheepishly. With every passing moment he regretted the idea, turning nervously as he heard his friend let himself in. His fear culminated in a nervous "don't be mad-" before any other greeting could form.
