Because I don't have a sister in my family so I'm jealous

I've been thinking about this for... few weeks... since I got surround by my friends who have sisters and their sisters also my friends...

It must be nice to have sisters... little sis or big sis... with the same hobby, same interests...
So you can fangirling together, travelling around the world, shopping around the mall or just hanging out together... must be nice eh :/

Well I do have friends but friends cannot stay with you 24/7 right~
Haa... I want a little sister/big sister actually...
My parents won't grant my wish... because I have 2 little brothers already :/

I always staring my friend with her sisters whenever they have argument or same excitement over something, it feels like I'm jealous but not actually jealous. I just really want a sister :/

Will someday I get a sister? :/ foster sister will be fine as long she wants to be my sister and wiling to have such otaku sister like me :/
