The poetry of leaving

I just sent out an email to everyone in the company where I work. It said:

Subj: Ruth __'s Leaving Poetry Appeal

After 13 years I am leaving [this company] on 14 September. Instead of collecting money for a gift, I have been inspired by the Amnesty International book Dear To Me (which has 100 famous New Zealanders' favourite poems and the reasons they like them) to gather together your favourite poems, which I will turn into a single edition book. This will be a reminder not just of my time at [this company] but the people who make [this company] special.

To take part, please email me your favourite poem or a link to it, and a short note explaining why you like it or why it's significant to you. All donations will be gratefully accepted, even from those of you I don't know and have never had the pleasure of working with.

I enjoy good poetry and I am looking forward to the results but here I will confess that one of the reasons I did it is that I enjoy playing with engineers' minds.
