Everyone doesn’t have to like you, and everyone is not going to like you. Try not to let it upset you. If someone doesn’t like you, don’t take it too personally – maybe they don’t like the way you look at them, or the clothes you wear, or the fact that you remind them of someone they didn’t like in 2nd grade. Learn what you can from them, and move on. There are many more people in this world that they may become friends with, and many more people in this world that you may become friends with.
