This is a Tema+Gaara (not TemaXgaara) fan fiction. I am fully aware that this is 5 minutes crap and it's not even logic (found out after actually writing it ' I don't think Tamari was able of writing yet when Gaara was born) but I hope you'll like it, it's the idea that counts.
So please enjoy:

It was a hot summer day when I was searching for a missing scroll. There was only one room left for me to enter. Inside was the only things I found: A diary, photo's, drawings and an old wooden doll.

"Congratulations Temari. Now blow the candles and make a wish!"
I blew. As expected of a wind user, all in one!
"I wish... I wish I had a younger brother!"

Dear diary. I know! I'll write to you as my little brother! When I get a little brother I want his name to be Renai, which means 'love'. I hope he'll look a lot like mommy, uncle and me. But I don't want him to look like nii-san or dad. I want him to be my little brother, just for me.

Dear Renai. Nii-san was mean today! He said I was small and that he was right because he's bigger. I don't mind if my brother is smaller then me, because I love him anyway. I hope mommy gets a baby soon.

Dear Renai. I'm training to become a shinobi one day. If I'm a shinobi I can always protect my little brother.

Dear Renai. Sorry for not writing so much lately. I'm working hard on becoming a shinobi, so that's why. I want to do my best for my little brother. I hope he'll become a shinobi one day too! Then we can go on missions together! I don't mind if nii-san's coming along too then, since it has to be a team of tree. But if my little brother and I are together, we'll clear any mission!

Dear Renai. It's been a year since I've got you. Today, I've become 6. Nii-san wasn't that mean today. He had made me a doll and said I should use that until I have a real little brother. Nii-san can be nice sometimes, but my little brother will surely be nice to me ALL the time.

Dear Renai. I'm so happy! They finally said mommy's getting a baby! They say I'll have to wait for a while, but I'm really getting a little brother! Daddy's looking a little worried lately. I don't understand why. Everyone should be happy because my little brother is coming right?

Dear Renai. Mommy's feeling sick lately. I don't know why. She looks pale and uncle won't let me see her. I hope everything's okay with my little brother tough.

Dear Renai. He's finally here! I have a little brother. Daddy doesn't seem happy tough. He seems angry and sometimes cries. I still can't see mommy. Nii-san says he didn't wanted our brother to be born. Maybe he wanted another little sister? I can't see my little brother jet.

Dear Renai, or I should actually say Gaara. That's the name they gave my brother. I think it's a kind of strange name. I got to see him for the first time today. He was crying a lot. He doesn't look like mommy or daddy. I think he looks a little weird. But still, it's finally my long awaited brother. Mommy is nowhere to be found tough.

Dear diary. Gaara isn't sleeping. He's always crying at night. But I can't be the one who goes and make him stop; daddy makes other girls do that. I talk a lot with uncle lately. He can see Gaara way more often, since he's a doctor. He's saying Gaara's a bad baby, but I don't think so!

That's where it stopped in the regular handwriting. There was only a small part in a much more adult handwriting:

Dear diary. I wish Gaara would love us. I wish my long awaited brother would love me back.

"G-Gaara! What are you doing in my room!?"
Without me even realizing I had my arms wrapped around her shoulders.

"...I'm sorry...Temari-nee-san..."
