I am so annoyed with my brother...ugh sometimes I wish I was an only child.

I would think that being an only child would be somewhat boring and lonely.   HOw bad can it be with your brother?

He borrowed my lucky pencil when he knew I had an important test today. And he knows I can't function without my lucky pencil during a test! :(

That's not cool!  I hope you did well in spite of not having your lucky pencil.  Siblings can be quite pesky at times!
