10. You are the only one who holds the copyright of making fun of them
The situation would o like this: You will be making fun of the other one and all of a sudden a “Stranger” also starts making fun of your friend. You weren’t worrying a bit if he/she was getting offended but now because of “intruder” with complete lack of personal space, you feel so offended that you both start giving a side-eye and make the stranger feel pathetic.
11. The two of you can be completely childish sometimes
But does any one of you care? Heck no! This is the person you will be fooling around, baby-talking, ranting, making jokes and playing around all the time. Its fun being childish around them.
12. You can’t imagine a life without them
You wonder how you were living your life without them and can’t even think of one without them in it. It’s like breathing air because that is how much you need the other one. And you miss them like heck anytime they are not around.
