Misfit:

Severus Snape sneered down at the students in his first-year class. But there were two that really caught his eye. One, a red-haired skinny young girl with deep brown eyes, was buried in the textbook. The other was a tall blonde with blue eyes who was attempting to tickle the red-headed girl. They sat in a corner, clearly at least close friends, if not close relatives, although they looked nothing alike except for their haircuts. The other students clearly shunned them, although the two girls were good-looking and appeared good-natured. Misfits, just like he was. But at least they had each other.
