Dear Eric: I sing as a volunteer in a church choir. Because I can sight-sing, was trained as a musician, and can sing alto, the music director likes it when I come. For me, singing is “work,” not “fun,” but the music director is very nice, and the choir members are very warm and kind people. What I don’t enjoy is that one of the newer members wears very strong cologne, and I am allergic to it. If I forget to take an allergy pill before church, I cough during the entire service and sing about one quarter of the notes.
