Leaving Application(请假申请）
Dear manager,
My sister's wedding will hold on this Friday，can I ask a leave for attending it？

Ask for Leave

I will participate the wedding ceremony of my older sister's, please allow me to be absent for one day, thanks!

我的翻译如下：
标题： Ask for one day off
Please be so kind to get your permition for one day off as I am going to participate the wedding reception of my sister's on coming friday.
下面签署你的名字和日期
有一点说明：我们中国的风俗‘婚礼’指的是结婚酒宴，英语词是 ‘wedding reception’。
