回复：请教美国老土和其他前辈，

闲着也是闲着。 假设俺是高高兴兴离开的，俺就高高地说。

Looking back on my X years with X company, it is a tremendously rewarding experience, both professionally and personally. We’ve succeeded in getting the x product underway. I feel blessed to have gotten to know and interact with so many outstanding people in this company. I hope that my contribution left good memories with you all. I will always treasure the wonderful friendships we have made.

I wish everyone success in your pursuit/endeavors, hopefully our paths will cross again someday.
