Reflection About 2015

They have been really encouraging to us year 7’s for ne...

They started being best friends and one day her best friend came over and asked her if she could play one day and her mother said no because she had to finish off her homework. She didn’t like it that her mum stops her from going to play with her friends she said to her mum in a loud voice “IF DAD WAS HERE I COULD DO WHATEVER I ...
