If you have a little brother you have a built in best friend. My little brother is 5 years younger than me and I swear we are the exact same person. My little brother is "my person".

He was your practice baby

Especially if you have a larger age gap between the two of you, when he was first born, he was your baby just as much as he was your parents' baby! You loved to help get him dressed, hold him, help him take his bottle, etc. He was even better than a baby doll!

You'll Always Have Someone To Hit The Gym With

And the day that he starts benching more than you will be a proud day, indeed.

You'll Always Have Someone To Learn With

Whether you have the same views and opinions or not, you'll always have someone to learn and grow with. He looks up to you (even though you're positive he's smarter than you) and that will encourage open-minded discussion between the two of you, from childhood to adulthood.

He'll Watch Anything With You

When you want to watch Gossip Girl or The Bachelor, he's down. When he wants to start New Girl or House of Cards, you're down.

You Can Encourage Each Other's Relationships With God

You both grow at different paces but he's someone that you know you'll always be able to talk to about your relationship with God, and his optimism and spirituality will inspire you to grow deeper in your faith.

He Knows When You're Selling Yourself Short

Whether it's with a boy you're dating, a friendship, a job, etc, he values you and isn't afraid to let you know when that boy you're dating isn't good enough for you.

He'll Make You Laugh Constantly

He gets his sense of humor from you.

He's manly, but since he grew up with a big sister (you) he's in touch with his feminine side

From playing Barbies with you when you're little to giving you his opinion of your outfit now, he's not afraid to show his feminine side.

You realize one day that he suddenly towers over you

When I came home for summer break, my 8th-grade brother had sprouted up and is now almost 5 inches taller than me!

You blinked and that little baby doll is grown.

No matter how old you and your brother are, it will always shock you when you realize how old he's getting. From his first day of kindergarten, to his first day of freshman year, to the day he applies for colleges, to the day he gets down on one knee for the woman he loves, it will make you so glad that he is a part of your life.

Now ladies, go call your younger brothers and let him know how much you love him!
