Sorry it took so long to write back. Well..... 
 My brother is 16 months younger than me, so it's almost like we're twins (annoyingly so, in fact.) People always thought we were twins (until he got taller than me last year! argh!) It can be fun...you always have someone to hang out with, he understands my jokes (we have a lot of inside jokes) and he's an orange belt in kung fu, so he can beat up any weirdos who mess with me! ^_^  
 It can also really really suck, cuz he can be soooo annoying. but i love the little tyke anyways! ^_^ luckily he's got a good friend (his name's Lakota...no he's not Indian) so he doesn't bother me as much anymore. (phew!) anyway...it's both nice and tough....i dunno.  

 I AM CRAZY AND I DON'T CARE! ^_^  

 welp, gotta go for now.... 

 serious question, though: what's it like not having siblings?
