Celebrate National Sisters Day by tagging your sis in one of these LOL-worthy memes

Today, August 6th, is National Sisters Day. And whether you love her, or love to hate her, these memes will make you think of her.

According to a 1996 study from Penn State University, by the age of 11, children spend 33% of their free time with their siblings. That’s a lot, and it means that siblings — sisters especially — develop super special (if sometimes crazy-making) relationships.

In honor of National Sisters Day, we rounded up some of the funniest family memes we could find.

Are any of these you and your sister? Tag her in one — or all!

Sometimes you’re dressed alike.

You will fight for your sister.

But I just want to love you!

Don’t tell mom.

I haven’t seen your shirt, hun.

Don’t you dare come for my sis!

You’re so annoying!

Girl, why.

I hate you but I love you.

It’s not my fault you have a cold, dead heart.

Even if you don’t have a sister, or if you don’t get along with your sister, these memes are still funny. Sisters have all types of relationships; some are as close as the Kardashians, and some may be as competitive as Venus and Serena. (Serena has won 72 singles tennis titles, including 23 Grand Slams, while Venus has 49 singles titles.)

It’s unlikely that your sister is a duchess, like Kate Middleton, but it hasn’t changed her relationship with Pippa. And let’s not forget our fist sister idols, Mary Kate and Ashley Olsen, who were literally the same person for the first eight years of their life.

If you have a good relationship with your sister, tag her and show her that you love her. And that you’re still mad about that nail polish she spilled when you were 13. Happy National Sisters Day!
