This is going to give a whole new meaning to your best friend practically being your sister because literally, my best friend and I could not be more sister-like unless her parents adopted me.
You'll miss her pets more than you'll miss her.
I hung out at my best friend's house so much this summer that I literally moved to college and started missing her dog. I don't own a dog, but I spent so much time with hers that I was basically part-owner. Call me crazy, call me weird, but one day you might be lucky enough to experience this too.
You'll join in on their family holidays, and vice versa.
Last Thanksgiving, I participated in a family Taboo tournament. Last Christmas, I actually couldn't make the festivities because I had my wisdom teeth removed and the thought of not being able to eat any of the food at her house made me depressed, but I did get lots of best friend visits and lots of chocolate shakes.
Her parents will have dirt on you.
If we're being honest a lot of my top ten embarrassing moments have happened at my best friend's house with her family present. After about a day of red-hot embarrassment, it becomes a running joke. To this day, every time I go over there I still have to deal with comments about how I broke their dishwasher door last spring.
You'll get care packages from both your best friend and her mom.
Double the presents, double the fun!
When you're both home from college, you'll basically live at each other's houses.
Sleepovers, movie nights, forcing your best friend to get up and workout at the crack of dawn every morning when you should get to sleep in because it's summer, and then eating copious amounts of snow cones and making excuses like, "It's okay, we worked out this morning!"
