Coming of Age......bummer

So as I look back to when I was 10-11 yrs old I remember having a couple of really good friends. I considered my BEST friends (now-a-days its called BFF). I had other friends too that I would talk to or play with at recess but mostly just a couple of us that were always together. I have since lost touch with most of them. I just recently found my bestest friend from that time on Facebook. Funny thing is we have a TON in common even now...some good, some not so good. Anyway, when we were younger things happen, things get said, or maybe we just evolve and grow apart. I have noticed, with my experience and now watching my oldest daughter, that it is mostly because girls are just plain mean. I remember girls I grew up with and I still hold some resentment because I know I did nothing to make them treat me the way they did. It was just fun for them. Now I watch my oldest go through the same thing. She is far from perfect...boy do I know this first hand. What I can tell you is that she has such a big heart and it kills her if she hurts someones feelings. You could call her names and beat her up but she will not retaliate. She willnot stoop to that level. She is always thinking of others and what she can do to make them happy. This includes her friends, even if they are playing a game she doesnt like or make fun of her for doing something they think is silly. She stays true to herself and for that I am VERY PROUD of her. I watch her outside playing and most the time she looks like she is having fun....as 10yr old should. But it breaks my heart when I see the kids avoiding her and playing mean tricks on her. Telling her if she wants to play with them she needs to put mud on her face. Really, put mud on her face??? I know when she get older she will love it (facials) but for now to play with these "friends" she needs to put mud on her face??? Or when she asks one if she can play she says "no" then she goes to the next girl and she says "no". Five minutes later they are both out playing so Hailey will run out there to play and they will run from her and hide. Then of course Hailey is crying because she has no idea they are being this way. I told her girls are just mean. Then, because she is frickin smart, she says I am a girl and I'm not mean. These are the same girls who a year ago told her dance was stupid and for weak people and not atheltic. So after that she didnt want to do dance anymore. She was good too. I am amazed that girls are still so very mean. I am just going to have to figure out some super fun stuff to do with her during these mean episodes so she can cope.....Girls are mean...no wonder why MOST of my friends in H.S. were not girls!
