I havent seen it much but it is happening all around me. The look of longing for that someone will notice you and know that you like them and hoping if you like them back. I have it. My friend has it. When you stare at that person and you know that he might be the one but he doesnt evan notice you. You might want to talk to him but you cant. HE has to notice you before you do. If theres a dance coming around just mention it infront of him. If he doesnt get the hint then wait somemore. Love is patient.
