No, you don't need to change to be like other people. I can tell you right now that other girls your age play with toys, you just haven't met them yet. I'm 3 years older then you, and I still like stuff animals and Littlest Pet Shops.You enjoy playing with your toys, right? Do you really want to stop having fun just to be like other people? To 'fit in'? Won't you miss how you were before? The way you act, and the things you do are what define you, and if you change them, then you're not really you anymore. Just another copy of the same trend. So don't stop doing the things you love because you feel like the odd one out. If toys make you happy, then don't care about what the people around you think. Yeah, you might be picked on a little bit, but you're still having fun when you play with your toys at home. You'll still make friends that have the same interests you do. You're still different and special. Live your life for you, and do what you love. Don't let other people change you.
