Are there any other younger mothers out there who sometimes feels like you don't fit in with the "mom circle"?

I know the feeling all too well. I am 26. I have two biological sons who are 3 years old and 8 months old, and then I have an adopted daughter from my husband who is almost 12 years old. Whenever I take her to ball practice or school events, the other parents stare at me like I am her older sister. They don't really talk to me at all. I consider myself to be fun and outgoing. I listen to rap and wear juniors clothes. My daughter loves hanging out with me because I crank up the b in my SUV when I take her to school and the boys in her cl have crushes on me. She thinks that is hilarious. I still cook breakfast and dinner and clean my house and go to PTA meetings, but I rarely talk about those things. My conversations usually steer more towards business and political science considering that is what I majored in. My husband is ten years older than me and his friends' wives won't talk to me. The last thing one said was that I had really good skin. I told her I was 25 (at the time) and then she started making accusations toward her husband about being around younger women. Crazy!!! We all went out a couple of years ago and then went back to her house. My hubby seft me in the kitchen with the other wives while he and his buddies went outside to drink beer. All the wives talked about was feeding and how advanced their children were. Then, when I tried to talk about mine, they just stared at me blankly. I finally went outside with the guys. I know the feeling. I have gotten to the point that I just hang out with my real friends, married or not, or hang out at my house.
