The pastor might always be at work when another human is nearby. She needs some friends - friends notice, because friends you let see.

Your poem is really really excellent. Succinct (yes, even you can do that), simple and pure. The use of the invitation as a foundation is brilliant, and very effective. I think anyone who finishes the poem will see the invitation's purpose in the piece. For me, the missing invitation (to a marking of a passage), is left in the ether, but very much there, just like the lost life. No final line is needed. Let those who really understand the poem feel the unsent invitation, or the invitation in the mail, whichever they would want to do. I really love this thing, it's perfect.
