When in doubt, make people laugh.
No matter how bad it gets, make people laugh. If you don't know an answer on a quiz, even though you've studied for it, come up with the funniest answer possible. Chances are, you'll still get it wrong, but then you'll come off as funny instead of lacking in intelligence. You might not get out of trouble, but make 'em laugh.
If you're shy, make someone laugh. Any way you can. Handle it with laughter. If you've got an accent, you're clumsy, or anything like that--just make them laugh.
You'll do fine, loves. Just make them laugh.
It took me a long time to figure that out. Many, many years of sadness and being bullied.
Don't take as long to realize it as I did, my loves.
