People Aren't Always Who You Think the Are

In the book Julius Caesar which I am currently reading I have seen that Caesar has some friends that aren’t really his friends. He has Brutus which he thinks is one of his closest friends that ends up stabbing him and taking part in his assassination. In life people might act like they are your friends but they might just be using you to get closer to other people or to just get stuff from you. The point of this is that people aren’t always who you think they are. Even your best friends might not even be your friends.
