Back in the days when we used pianos to accompany the singing, I very bizarre sister would visit our congregation once a year. Her singing (like her speaking voice) was so loud and strident that it would actually disrupt the singing overall. She told me she played the piano, so I thought great, I'll ask her to play the piano. She readily accepted. I felt a feeling of accomplishment until it was time to sing the first song. Not only was her piano playing almost as bad as her singing, but unlike most of us who played the piano for the meetings, she played and sang.
Had I not stopped attending meetings two years ago, I'd still be getting flack for this.
