During a potluck dinner in Beijing Adel brought an dish made from pomegrante seeds. It was in December, the crowd was not used to the fruit salad dish. Adel was the only Iranian there. A talented cook as Adel was, the dish was barely touched. Adel, I think you would agree with me that international potlucks are as bad as they can be. Let's hang the fruits high up - trees are good to store and access memories. For the pomegrantes seeds that I've missed that evening.
