According to the well known "Elders guide to the universe",
An elder may shepherd at the publisher's home,
at the Kingdom Hall, while in field service, over the
telephone, or on other occasions.
So maybe a shepherding "call" was made on you while you were at the KH or you got
a phone call. Or maybe when you were going from door to door. I wonder when
sherpherding will be done by a text message or by email, as this might well come under "other occasions".
Sample shepherding template:
Hi Brother ____________
How are you?
We miss you.
Why are you not commenting/ attending meetings / going regularly on field service /
(insert other criticism) ___________________
Read the Bible more.
Have a good day.
(End of shepherding text)
