The scene: One guy. One girl. (Ok, ok. It was me.) Hang-out buddies clearly interested in one another. They hang out at birthday parties, movie nights, and pool parties. A month goes by. There’s lots of texting and chatting on the phone, but still no date. After another month of this, boy and girl rarely see each other and hardly ever talk. Why no happy ending for these two? Simply put, hanging out had become a habit too hard to break.
