I grew up being the only daughter in a family full of boys. I have three brothers, (two older, one younger). They are all idiots and wonderful in their own special ways. I love each of them and I would never trade them for the world. Here are the benefits of growing up the only girl.
First, there's a lot you don't have to share. My brothers grew up sharing everything. They shared a room, clothes, toys, etc. While I had to do the normal sibling sharing, I always got my own room and never had to share clothes. It was easily one of the greatest perks of being the only girl. As an added bonus, I was able to steal giant sweatshirts and T-shirts from them when I wanted something comfortable.
Second, you always have help with the heavy lifting. My brothers were there to help with everything from moving furniture, to lifting boxes. I am physically not a strong human. I am short and do not have muscles. I am so thankful to have brothers to help me out. It's always helpful when you live with your own pit crew.
Third, you always have a bodyguard when the situation demands it. My brothers are always there to get me out of a bad situation. Uncomfortable on a bad date? Brothers will not only help you out, they will terrify the guy into leaving you alone. Is an obnoxious guy hitting on you? Brothers will make sure he never makes that mistake again. I knew I could always call my brothers over when I was uncomfortable or scared.
Forth, you are able to appreciate things that are more stereotypically boyish. While all girls can enjoy generally boyish things, it's easier to be introduced to it when you're the only girl. I grew up loving comics, videogames and playing in the dirt. Thanks to my brothers I'm not afraid to get dirty and they helped me discover some of my top interests and hobbies.
Finally, you have a unique relationship with each of them. when they need advice with girls or want a different opinion on a topic, my brothers will always come to me. To them, I'm the one who will always give them insight on what a girl might be thinking. This means I'm extremely close with all of my brothers in different ways.
I loved growing up with three brothers. It had a large part in shaping me as a person.
