How to be Smarter: When you intially send someone an email, address them by the most formal way you can. "Prof. Thomas" for your teacher; "Elizabeth" for your RA; "Mrs. Leigh" for your friend's mother. After they respond, you can address them by the way they sign their email, i.e. "Prof." for your teacher; "Liz" for your RA, "Cheri" for your friend's mother. How to be Prettier: Use a shade lighter than one's skin tone to cover an inverted scar with. This creates the appearance of a smooth surface. Using a shade darker than natural skintone on a raised scar will have the same effect (source).
How to be (less) Awkward: Don't watch movies that scare you. It is not childish to say you don't want to watch something-- but it is childish to feel peer-pressured to watch something you don't want to.
