I enjoy listening changes.It doesn't make me happy.It isn't a happy song.It pleases me to listen. Does pleasure makes us happy? Does pleasure always makes us happy? Do we have to be happy to get pleasure? Define happy? Do we have to smile when we are happy? Or is it just peacefullness? Do we have to suffer first to be happy?if so why does a baby smiles?Can we be happy with hormones? Even when we hit rock bottom? Or is it just a good surprise that makes us happy?
