Jazz Band… (will I join or not???????????????????

This year I had a choice to go to jazz band and I wanted my brother to check it out and see if he liked it or not so he went. A few months later, he said I don’t like it so much so I don’t think I will go but……….. I MIGHT CHANGE MY MIND??? My thought of me going to jazz band and performing on stage is a yes but also a no so it’s 51 percent yes and 49 percent no.
