I was attending a fairly large service in a cathedral, and realised I was quite high-up amongst the clergy present, though not delivering the service itself.
I seemed to be wearing a cardinal's robes, and was being pushed around respectfully in a weelchair... I felt like a terrible fraud, being neither a cardinal nor unable to walk. I rose from the wheelchair occasionaly to make my way on foot, out of embarrassment more than anything else, but this merely appeared to attract further quiet respect from those around me.
The congregation were not seated in one assembly, facing towards the chancel, but rather in a cross shape facing a central altar.
