1) She is your biggest fan.
I'm not kidding when I say biggest. Whether you got a tremendous or awful GPA last semester, you best believe that she has told all of her closest friends as well as all of her second and third cousins how smart her grandchild is, and how proud she is that they are attending college. Whether or not you know it, she loves seeing your Facebook pictures to see what you are up to, and uses it as bragging rights to all of her friends.
2) She gives the best advice.
While you may think that she "just doesn't understand" us Millennials, think again. Your grandmother is basically an encyclopedia for advice. She has decades of experience on you, and has been through just about everything in the book. She understands and has advice for every kind of drama in your life, not limited to but including boy drama, girl drama, friend drama, parent drama, and sibling drama. Next time you are in a stressful situation, make her your go-to girl.
3) She is a wealth of historical knowledge.
A lot has happened in the world in the time that your grandmother has been alive, and you might be surprised with the stories she has to tell from her point of view. Who knows, you might learn something interesting about your heritage that you may not have known had you not talked to her.
4) She cares about you in a way that no one else does.
Do you know anyone else that cares about you enough to take the time to mail you a card on Halloween? Or to carry your school picture in their wallet? She is always thinking about you, and would do absolutely anything to brighten your day (and whether you know it or not, you always brighten hers).
5) She will never judge you.
She always thought you were adorable, even when you wore blue eyeliner and tried to do your hair like Snooki. She will love you and will be proud of you no matter how many fights you get in with your parents, whether you get bad grades or not, or whether you are single and have thirty cats.
Let's take the time to appreciate our grandmothers - after all, they are pretty awesome ladies!
