"Do not enter" was written on the doorway of your treehouse, it's where you sit and talk really loudly, usually you're all by yourself, "why can't everyone just go away..?", but you hear a knock on your door.

"Hello..? It's me, Robin, can I come in?"

Well, except for her, she can come in anytime, she's a nice person that always makes you laugh, and thinks you're so funny, the second she comes in.. you're not gonna let her leave anytime soon.
