Sarah,

Thanks for you inviting dinner. I actually wanna go to dinner with you, but sorry, I have schedule already on today and tomorrow, and there was employee movement in my company, and I moved, so I have to attend farewell party which my subordinate and agent people invited me.

And next month, I have to attend welcome party.. I eat and drink every day, I might gain weight when I meet you next time.

I look forward to see you, and please keep it up with your job!

Thanks,
Yamada

Sarah,

ディナーのお誘いありがとう。本当はとっても一緒に食事したいんだけど、ごめんね。今日も明日も予定があります。人事異動があってね、平日は送別会です。エージェントや部下もたくさん誘ってくれて本当にありがたいんです。来月も新しい部署で今度は歓迎会です。
飲んで食べてばかりだから、次回会うときは太ってしまってるかも。
次に会えるの楽しみにしているね、お仕事がんばってね。
