I'm not sure they are absolutely essential. I mean, if I have a birthday party with friends, then sure, why not have some music and dancing; it's a great way to have some fun and relax with friends. However, if I want to talk or catch up with friends, then I don't think they are essential. Having people around me that I care about while having a party in a restaurant or the park is just as fun as having one with music and dancing at my home. The most important thing is to have a laugh and enjoy yourself.
我不确定它们是否绝对必要。我的意思是,如果我和朋友们一起开生日派对,那么当然,为什么不放点音乐和舞蹈呢?但是,如果我想和朋友聊天或叙旧,我就不认为音乐和舞蹈是必不可少的。在餐厅或公园举行聚会时,身边有我关心的人,和在家里举行有音乐和舞蹈的派对一样有趣。最重要的是开怀大笑,尽情享受。
