15 Best National Siblings Day Memes To Share With Your Brother Or Sister

Happy National Siblings Day!

And if you're an only child, congratulations! You don't have to put up with the craziness that is sibling rivalry.

You may be thinking that you had always wished for a sibling, but let me tell you, my friend, it wasn't easy growing up with an older brother and sister.

Yes, I'm the baby of the family, but that also means I was the target of the family.

When I was a wee little one, my brother who knew I was terrified of Freddy Krueger, created the infamous hand out of plastic knives, a hockey glove, tin foil, and masking tape.

One night after I had fallen asleep, he slowly opened my bedroom door and scraped my walls resulting in that bone-chilling sound that Nightmare on Elm Street made famous.

It's always good to have a backup.
