Well I remember I'd say "I am not going to die" whenever my parents ask my health condition. I am sure I make them anxious by saying that. ^^
So I can say your experience with your siblings was pretty good. I am not sure if I can get along with a brother or a sister, but it would be exciting to have one anyway.
BTW, what happened to you recently? I remember you said you are usually busier during summer break, so were you back to school already? It would be good to see you around more often on the internet.
I have been discussing with two partners during this weekend and I am about to merge my forums with theirs. The new community will have a total of 450+ members, 28000+ posts, and I am sure you will enjoy making new friends. ^^
