Life With Poly-Amorous Parents

My parents are like any other parents. They both work, both drive cars, both provide clothes and shelter and love for my brother and I. But there's one major difference between my parents and say, your parents, for instance (pardon me if I'm lying, I don't really know you, just an example). They are poly-amorous. This means that they are in love with more than one person (or can be). I know it sounds really weird and strange but they are my parents. They are pretty normal, save the stuff that I don't want to know about (what goes on behind closed doors, if you get my drift.) This has always been a big problem for me. One time, my mom's *friend* was telling their neighbor about their relationship w/my mom. In one genius move this woman (the neighbor) almost made my life miserable. She told her son about my mother (don't ask why), who, in turn, tormented my little brother (they were in the same recess). This was probablly one of the worst times of my life. I was scared to death that this little boy would end up spreading these horrible (but true) rumors about my parents to my school. But I kept it in. Because I was embarrassed. Now, everything's fine....my little brother is in the same school, but the "bully" moved on up to seventh grade....I'm kinda hoping karma finds this kid and kicks his ass. But my parents don't tell me about what they do, and I don't ask. it's not so much a problem anymore, and I don't let it interfere with my life. But I also don't talk about it unless people ask. It's not like it should be broadcasted (although, I'm being contradictory by just writing this....), but I do think that people should know one thing: just because my parents aren't necessarily normal doesn't mean I'm not normal. I mean, not only that, but what is normal? I'm a teenage girl trying to figure that out, but if you do know me and you do know my parents, who cares what they do? It doesn't, and shouldn't, concern me.
