Looloo

I'm 11 years old and when Summer's over, I'll be going into 6th grade. My auntie (or tia, as they say in spanish) told me a lot about Postcrossing. I'm sure this will be fun. The only way I know some Spanish is because it was one of my classes at school. I wouldn't like to receive postcards with churches, religous sayings, or cartoons. I would like to recieve postcards with peoples flags on them. Of course, if you can't, that's fine. Either way, I'm excited to receive you're postcard. I love to perform. In the post card that you send to me, I would love it if you could tell me something in the language you speak and if you could tell me what it means in English. Even just a word would be wonderful. On you're postcard please put if you are left - handed or right - handed. I'm left - handed. Also, please put a pet peeve of yours. I can't stand towels against my finger nails. Also, if you could please put a habit that you have, that would be great. I have a habit of playing with the hair ties around my wrist.
I hope i'm not asking too much.
Thanks!
