Let's face it: growing up with siblings can sometimes be... challenging. Don't get me wrong, I absolutely LOVE my "little" brother, but we weren't always so nice to each other (and sometimes we still aren't)!

In case you haven't figured it out, today is National Siblings Day. According to a survey from National Today, a whopping 89% of people have a sibling. Most people say they are pretty similar to their sibling, but 19% say that they couldn't be more different. The three most popular words people used to describe their relationship with their siblings are love, support, and fun, with 10% even saying that their sibling is their best friend!

I'd have to put myself in the 19% of people who say that they are nothing like their sibling. My brother and I are total polar opposites. Because of that, we don't always get along, but that doesn't mean I don't love him to death! Here's an old photo of us that I was able to dig up this morning:


Now, there is one part of the survey that I have yet to get to, and that's the 8% of Americans who have "physically fought with their sibling(s), drawing blood or leaving marks." I'm happy to report that I don't fall into that category, although my brother and his friend did once chase me around the front yard and shoot me with pellet guns...

In honor of National Siblings Day, we want to know: what's the WORST thing you did to your sibling growing up (or your sibling did to you)? In could have involved a physical fight or psychological warfare, and it could've been on accident or on purpose! Share your stories with us in the comments below!
