If often happens in parishes the Bishop visits for Confirmations that a group photograph is taken just after the recession. Consequently, I don't always have the opportunity to thank the mitre and crozier bearers before we leave. I can thank the other servers who are ahead of me before they return to the sacristy, but the mitre and crozier bearers have a knack of returning to the sacristy before I have a chance to turn around.
With this in mind, I sometimes offer a sign of peace to them and thank for their help. When I did so last evening, the mitre bearer asked, "Are we done now?"
I may have to find a new strategy.
