Speak up. When something doesn't work. When someone is being hurt. When you don't agree. Speak up. Someone has to. It's a burden to see more, it's a duty and a privilege. So take care and speak up. You would be surprised how many people think the same and are equally afraid to speak up. Someone has to be the first.
It’s not always easy to speak up, even more, if you’re the first. Good for you if other voices join yours. But if not, that’s ok too, even though some people might not like what you are saying.
