So my answer would be, well honestly to my mind, food is so important because it brings out a communal aspect when everybody is eating together within the celebration, the party, the event, whatever, any time huge groups of people get together, food is always an important part.
我的答案可能會是:我想食物之所以如此重要,是因為它能帶出共同社群的一面;每當一群人聚在一起慶祝,在派對上、任何活動場合裡,食物都非常重要。
