When a girl does this.

When a girl says, "I'm sorry" it really means she wants you to say sorry to her and reflect on what you did wrong.

When a girl says, "You're a jerk and a liar and a player" in a humorous way; she means that she's jealous of you hanging around with other girls.

When a girl says, "I love you" she wants you to know that you're the only one who can fill her heart up.

When a girl starts to laugh for no reason, she wants you to know that you're not just the one whom she loves, but a friend whom she doesn't want to lose.

When a girl says, "It's over and I like someone else" she wants you to know that her heart is falling apart because of what you did. "I like someone else" isn't really what she wants to say; she just wants to test you, if you are going to let go of her that easily and move on.

When a girl says, "I miss you" she wants you to know that you're the only one who can fill up her time, even if it's 24/7.

When a girl rejects your hugs, it doesn't mean she hates you, but she wants to tell you that you can't just hug any girl you want. She's the only one you can hug.

When a girl yells at you, she wants you to know that deep down inside she really cares for you, in order to waste her breath and argue.

Although when a girl does anything that you don't understand, it's maybe because she wants you to understand her a little more.
