it was strange at first but then you realized. Your friend Kelly (circle) was coming to school with rashes on her arms almost everyday. At first you thought that mabye she got a really bad injury from being outside but then more appeared eventually which you got suspicious of. Long story short, for every bad grade Kelly (circle) got her mom would beat her with a ruler until she bled. So you got her mother arrested and decided she could live with you. And so she became your step sister. Although she was still traumatized....why not cheer her up :3
