I like both versions of the song. But I like kesha's more. Yes Miranda's giving more like a tsundere school girl vibe which is alright, but kesha had more of a feel of hatred in the lyrics and her voice. Kesha's version made me relate to the song even more. Like the song itself is about "not wanting to be attached to someone" because they were hurt before. Because when I get the feeling of having a crush on someone i feel like panicking or something and i want to get away from them, because "I've been hurt before". As older i gotten as a teen i had trust issues but until i did met someone once. They said they liked me before they gave me affection and understood my problems like they always did when we were just friends. I was for sure we would be together. But later on in our relationship, it turned out it wasn't meant to be. I really don't want get too attached to anyone. Now i feel like if next time a person tries to get close and show affection to me it would be the same as always and I'll get uncomfortable. I just don't want to fall for anyone again. When I develop a crush I want to kill them because I hate having those emotions.
