The message
from Chris Bacon contains these words:

[tightening compression fittings]
Doesn't everyone use two spanners? Perhaps that's where all the people
who've been having compression joint fittings are going wrong, they're
just using one spanner!

Don't you *have* to use two spanners (or a spanner and a "grip", or
two pairs of Stillsons)?

I'd have trouble doing otherwise, but I was wondering whether failing to
do so might be the root of the trouble people are having with
compression fittings.
