Stuck In the MIDDLE (of a friends' releationship)

During Middle school ESPECIALLY if your in a prativte school. Theres one experience that is the worst and most common, your best friend dating another one of you best friends. I don't mean same sex, I mean guy friend and girl friend (NOTE TO SELF: WRITE POST ON GAY MIDDLE SCHOOLERS). It's normal to wish their realtionship is over and to tease them all the time (or whenever you get the chance). Though you start feeling left out. Whatever, there realtionship will last. You don't want to think of what their doing togather, or what there thinking. IT CAN BE SOOO DISGUSTING!!! NO ADDVICE ON THIS SIDE!!!
