I'm overhearing a conversation about siblings right now. The two people involved are discussing girls and how having brothers made them "tougher" and "just different". As this conversation went on, these two seemed to imply that girls without brothers were "wimpy" in some way because they didn't have brothers to beat the hell out of them.
So, guys and gals, what do you think of this theory? It can apply to boys as well who maybe only had sisters growing up. I found it ridiculous, because having three younger sisters growing up seemed worse than having brothers.
Alternative topic: what is your role as either a sibling or an only child in your family? If you had brothers and/or sisters, how did they affect the way you grew up?
