I find it really difficult when people come up to me and say "You sang really well", or "Thank you for singing at mass today". It is as my singing has become the focus of their attention instead of their singing to God. I feel a little defeated by this, because in that case I feel that I have failed in my objective.
This week, I led the singing of Willcock's setting of Psalm 51 at mass twice in the Cathedral. Each time it got responses. I said "Well, Chris Willcock has written a very beautiful setting" or, on another occasion, I led the discussion into what the psalm was about.
Sometimes, when complimented, I just have to say "Thank you".
