no thanks I'm not gonna let idiots ruin my day. Be yourself no matter what other people think. Trust me you'll make much more friends and have much more fun. If they think you're weird they're not worth it.
There's no point in consistently worrying about everything. What will happen will happen regardless. So breath, look on the bright side. Have some laughs, fall in love, accept what you can't change, and carry on. To actually live is courageous.
