Usually when you think people are staring at you, it's one of two things.
1. You have a hideous deformity that commands attention.
2. It's all in your head.
Do you have a hideous deformity? If so, you should be used to the staring by now. If not, stop being paranoid. No one is staring at you. Are you staring directly at them to figure out if they're staring at you? If that's the case you're probably freaking them out with your staring, so that's why they appear to be staring at you.
Live as if you were to die tomorrow. Learn as if you were to live forever. - Mohandas Gandhi
