Watching who your friends are

Not everyone is your friend. They talk about you behind your back, make fun of you when your struggling but expect you to give them things when they are in need. They will never be there and be fake towards your face and be opposite behind your back. They stab you in the back any chance they get and watch you rise as they want and wishing you'll fall. They are not your friends. Ask yourself who was really there when I needed help? Who can I count on that will not stab me in the back and make fun of me?
