谢JJ.硬着头皮写E文回你吧:

Just sent him an email(which I usually don't do, except replying his:)), saying that since he already has X-mas plan, if he is here on his B-day, I would like to throw him a party. I could invite some people and so does he. And I will buy a nice cake. I thought about inviting him to my home with a lot other friends on Thanksgiving (a white lie here :)), but he will be at Mexico (this is the fact anyways). So I would like to celebrate his B day as a compensation because I want to thank him for his time and consideration on me.
Forgive my poor English here, need more study :)
