急，帮忙翻译一下。谢谢啦。是宴会邀请函的回复。

I hope very much to attend your graduation party, and I believe that this will be very interesting. But it's a pity that my parents have already invited some of our relatives to come for re-union, therefore please kindly let me know if you will be able to visit us this Saturday evening, and tell me details of your party at the time.
