Can one's feelings be effective?

My father and mother were both orphans before they married so my father didn't know how to sing well and they asked him to sing in school and he said... "No, I don't want" "I don't know how to sing" so they forced him the teachers back in the days 'I say - You sing' so he sang and it sounded bad and all the kids laughed and he had emotional pain so he asked Hashem (God) his children shall be able to sing pshhh.. wow! he told it to me a few years ago and I was so overtaken by it so there aren't really any grandmothers grandfathers, uncles, nephews, brothers who can sing and there are two siblings in the family that sing professionally what a crazy story... right? tears from a father a father's tears
