So, technically I don't have a sibling. I'm an only child, so my siblings would be my walls (wth).
But I want to write a letter addressed to my sibling anyway, although I know the alternative was your closest relative because I'm insanely interested in writing to a nonexistent person.
Dear sibling (Whatever your name is),
I'm going to assume you're a girl. Not to be sexist, but I can't imagine having a brother, what with the Hot Wheels obsession and the very, very unsettling interest in erm... alternative movie genres. I remember when I was a kid, I dreamt of having a sister to talk to and play with. I even flicked through name books to find the perfect name for a sister. Well, that sibling did not materialize, so my hopes have been put out. Sad, but things happen.
Anyway. If I had a sister, I bet we would have loads of girly talking sessions. I might even bully you into doing some menial house chores (like washing the dishes, I hate it). I guess we would have our moments and fight a lot, but then again, bak kata pepatah Melayu, carik-carik bulu ayam akhirnya bercantum juga (haha, rojak language much?). I bet we'd be obsessed over K-Pop and fight over the cutest/hottest guys. I would be there for you when you get your heart broken for the first time and then seek out the offender so I can punch him in the face until he could see the faraway galaxy of Andromeda.
I wonder if we would share the same fashion sense, whether we would raid each other's wardrobes or constantly criticize each others' dressing. I wonder if we would have girly sleepovers and watch rom-coms non-stop. I wonder if we would both share the same eating habits. I wonder if you would like spicy food as much as I do. I wonder if you would love stuffed toys and (occasionally) act as childish as me. I wonder if you would go through the torture of braces, like how I'm suffering right now.
However, one thing's for sure. I would love you to bits, no matter how much we fought or yell at each other.
Okay, end of letter. Isn't it weird how most of the time only childs crave for siblings and those with siblings wish that they were only childs? :)
