At the end of every speech or presentation, I always ask if anyone has questions. I open the floor to everyone, students, faculty, staff, whoever. The response is usually the same: SILENCE. There is always someone in the group with a question that they think is funny, you know who you are. The 'look at me' question so everyone knows that you are there. I'm used to it, I know it's coming. And guess what, it's never funny.
But here's the thing. There are always those in the crowd who actually have a question, but they're afraid to ask. Why? Because they're afraid of what the other kids in the crowd will think about them. But you know what? They have the same question, and others, and they're afraid to ask too. I understand it's high school (or middle school, or even college) and that you care what the other person thinks. But you know what? Deep inside they'll thank you for asking the question because they didn't know the answer either. And in the end, who cares what the other person thinks? If you need to know the answer, you need to ask the question.
Be brave, be bold, and ASK THE QUESTION. We (and I) don't have all the answers, but we'll never know if we don't ask the question first!
