A theoretical Moral Dilema

Have you ever met someone new that looks EXACTLY like a close friend or family member that it's kind of weird? I mean to the point where if you took cut outs of each person and compared them they'd look like twins? Well there's a teacher at O'Ferral that looks EXACTLY like Andrea's friend Vanessa and it got me wondering if it would be wrong to unknowingly assigned to a family friend as your guide teacher? I mean there is no way they could be objective. If I was ever put in that position (aka- if Vanessa was actually a social science teacher) there's a part of me that would be like, "SWEET this should be a cake walk." b/c she's like another sister to me. But then they other part of me, and probably my mom too, would be like, "nooo, that's not fair. You should ask for a different guide teacher". THANK GOD I'M NOT IN THAT POSITION!!!
