The Pickett sisters - Mia (left) and Laila - participated in &quot;Mixed Chix,&quot; a multiracial affinity group that meets monthly at Seattle Girls&#39; School. Neither girl considers being mixed-race her primary identity, and they don&#39;t always bring it up. But they know it&#39;s a part of them. &quot;I know that I am mixed inside,&quot; says Mia.
