One of the most annoying things when my daughter was an infant, was when I would dress her up in girly colors(pink, or purple) and I had little headbands with flowers on her and she has her ears pierced. People would still ask if she was a boy or a girl!!
If the clothes didn't give it away I though for sure her pink flower car seat would.....nope!
The other thing that pisses me off to no end is...
I have a 200lb Saint Bernard who is highly trained for personal protection/guarding. I would tell people that he WILL BITE, no matter who you are, what age you are, or what sex you are. Some people will still attempt to pet him, or walk into my house without knocking on the door. I take all necessary precautions to make sure he doesn't bite guests or neighborhood kids(I lock him up or put him outside in the fenced backyard. But some people mainly my one neighbor, will still try on a daily basis to get near him, go out back with him, or try to come into my house when my husband is at work(BIG NO NO). I guess when he gets bit or attacked, he will learn? All I know is that I will be damned that my dog pays the price for their stupidity.
And my last rant
I hate going out to wal-mart or anywhere for that matter. It never fails that when I go somewhere with all my kids, I get asked if they are mine. I always feel like saying No, their not mine...I kidnapped them on the way here and I'm trying to sell them for a case of beer

Once they find out that all the kids are mine, I usually get a comment along the lines of...wow you must have started way young, I've never seen such a young girl with so many kids, what are you like 16 yrs old? OMFG no wonder why I don't play well with others.
