Though choir don't have the requirements of physical exercises or such so, I still felt debilitated. As if 3 hours is enough to make me feel worn out. Okay non-human, I know, I am too petty, but hear this out, petty to a non-human like you not to humans...mind that.
But whatever circumstances overcomes, I am too affectionate in attending Choir practice. I love singing like no one once before had ever thought of. But secretively to you, I had a minimal amount of stage fright. Meaning I could not present a talk or do anything solo on the stage, not the same as in group. I must at least needed a companion on the stage, highlighted when the stage was gigantic as any other stage(but despite the size, my fear will never fade when I am solely alone), not at all do I want to present on stage....Ooh no no. So you knew my phobia disease already... Make sure you, non-human, keep it sealed safely and securely.
