Last week, one of my pals here at Sugar HQ told me a frightening story. While talking to her younger sister, she mentioned a nightmare date she went on with a guy she met online. As she started describing the guy and his aggressive touchy-feely nature, her sister wanted to hear more. Turns out the sister had been out with the same jerk a few times before! My friend was less than pleased, especially since this man probably knew they were related and never said anything. Still, not all siblings-dating-the-same-person stories are the same. Just like with friends, your sister might recognize that her ex could be your perfect match or vice-versa. Have you ever dated the same person as your sibling?
