Rainbows in Threes

"MUM!!!!! Dream is being mean again!!" Minty Dew shouted. mother flew up to us. We were all perched in a tree, squashed up, almost falling out."Girls, come down would you? I can see why Dream is up here, but you two? why, you don't even have wings!"exclaimed out mother."Mum, it was easy." replied Minty."Sure it was, Misty Dew?"she said, looking at me."um, yeah. Easy..." I mumbled."Ha!"Misty Dream exclaimed."You guys almost brought the tree down trying to get up here! All I had to do was fly!" We both glared at her. All of us were the exact same, with rainbow manes, and white coats. The only difference between us was the fact that Misty Dream was a pegasus, Minty Dew was a unicorn, and I was an earth pony. Misty ws the oldest, by three minutes, then Minty Dew, and then me. Our manes are all the same as mums, and so are our eyes(a lialac purple), and we have dads coat. We wouldn't know though. He died, or something like that when we were little. But grannies coat was white as well, and so I think it might run in the family. White, blue, white, blue and so on. "Dream, would you please stop with the bad attitude!"said mum. Mum is brilliant. She never gets really angry. She's cool with EVERYTHING! Except when we get bad grades at school. But that was only Dream, when she was bunking off. Eventually Cherilee figured out what was going on, and so did Mum. It was scary when Cherilee found out, because she got quite angry, but then she phoned home, and told mum. When we got home, she told me and Minty to go to our rooms, but she held back Dream, and shouted at her all afternoon. It was awful....
