When most people think of the overprotective big sibling, they picture the stereotypical shotgun-slinging big brother, sitting on the porch on prom night, daring his little sister's date to bring her home a second late. But that's not always the case.

As the oldest, watching your younger siblings enter the dating world is... interesting, to say the least. We all want nothing but the best for them, right? And that means holding their significant other to incredibly high standards, and for good reason.

But when it came to my sister's new boyfriend, only one thing really mattered to me: does he make her laugh?

Laughter is the best medicine, after all. Luckily for me, my sister and her boyfriend, he passed the test.

And with that, my family welcomed him with open arms. I mean, a successful kid with a good head on his shoulders, who has plans for his future AND a solid sense of humor? How could we not love him?

But now he's getting ready to leave... for college, that is.

To the boy who holds my sister's heart, here is my advice as you experience the biggest change of your life: live, love and laugh as much as you can, harder than you ever have before. You have the next three months to make as many memories with my sister as you possibly can, so take every opportunity that you can. Even if it seems minuscule or cheesy, do it, because no act of love is ever too small.

Once these three months fly by, which they will trust me, you'll be faced with the enormous reality of college. You will feel every single emotion possible; fear, pride, excitement, etc. But as you take that first step into the next chapter of your life and every step thereafter, my family and I will be cheering you on, with my sister's cheers always a little bit louder than everyone else's.

You're going to face some obstacles along the way, that's life. How you chose to handle them is up to you.

And even though some days it may feel like you're a million miles away, you're not, and that is both a blessing and a curse. A curse because my overprotective momma bear side will come out if you ever hurt my sister, and a blessing because you will always be welcomed home with open arms.

Rule number 2857 in the Oldest Sibling Handbook: don't boost your younger sibling's ego. But alas, here we are, so let me just say this. She sure did pick a great guy. We cannot wait to witness all you accomplish in college and beyond. So spend your summer wisely, kick some ass in college and treat my sister right... or I'll kick your ass.

Now go get 'em, tiger.
