Meet My Siblings!

I have both a brother and a sister, though I only live with my brother.  My sister is a bit like me in the sense that we're both shy yet outgoing when comfortable enough, a bit of a geek, and a major cornball at times.  My brother, however, is the complete opposite of me.  Energetic beyond belief, and an extremely outgoing person.  He will start a full-blown conversation with a complete stranger!
