Almost all of the girls that is interested in me, ask others their opinion on me, doubt on me, and wants others advice whether should they date me.
Come on, I'm the one you are interested in, come ask me. I absolutely hate it, when you approached me the last, when I am the one you want.
I often lost interested in them, when I see this.
