Receiving praise, especially at church, used to make me pretty uncomfortable. Applause is easier to take than someone coming up and addressing me directly after I play, or after a service. I used to play it off like it wasn't anything special, but my wife pointed out that taking that approach is borderline insulting to the person who has gone out of their way to give you a compliment. It's basically like saying they don't know what they are talking about, and that they have wasted their time trying to pay you a compliment. Now I simply smile, say thank you, and that I appreciate the kind words. After all, we are the ones who put in the work and effort to make it as good as it can be for its use in the service.
