I won an award for the highest SAT score in my graduating class. They gave out the award at a combined ceremony for every school in the county, and it wasn't until the first student started talking that I realized I had to make a speech.
While I was scribbling notes on a napkin about maybe wanting to go to law school, the other recipients talked about charity trips to Africa, food drives, and saving the planet--I was pretty intimidated.
I ended up just winging it, and after it was over I got business cards from several people who told me that mine was the only speech that didn't bore them to tears.
Later on, nearly the exact same thing happened in a group interview for a scholarship I was applying for. The other kids were parroting what they thought the interviewers wanted to hear, and every time they were asked a question they'd try to bring the subject back to something wonderful they'd done. It sounded like they'd spent their entire time at school ticking off boxes on some leadership actives checklist. I didn't have any of those activities to fall back on, so I just treated the whole thing like a casual chat. I ended up winning the scholarship.
Apparently it's pretty clear when high school kids are just padding their resume with "leadership" activities.
