再瞎說一把～～

這樣試一下：

TMD VP，

It is nice peaking with you. I knew that your tasks would be very important to our company.

My current situation is that my work load is more than full with 大（小）老板’s assignments. With the requirements of （小）老板, I have no time to deal with another project. I am VERY SORRY about that.

Thank you,
--姑奶奶

CC：大（小）老板

---很抱歉，可能沒有幫助，看著玩吧～～
