Well, at your part time job, you can either smile and maybe make someones day, or be crabby and totally ruin someones day. So what does that mean? (I dont have the answer, i want you to answer it.)
You dont want to talk about your childhood, but siblings of special siblings are often shortchanged. I tried to be the least bother possible to my parents, since my brother was such a bother. They never even noticed, of course! But thats not how this life thing is supposed to work.
