Think of other types of stationery and write a letter from that object to me- it might be a glue stick, sharpener, ruler, rubber or whiteboard pen. Have a think what that item of stationery might be upset about. Here is an example to help you - you need to replace the sections in red with your own ideas:
Dear Ms Rogers,
I am your blue sharpener.
I love being used to sharpen all of the pencils in Campion Class but now I am feeling exhausted.
I feel like this because I get used all day long and get no rest.
I would be really happy if I could just get used at the start of the day.
I look forward to reading your response,
Blue Sharpener x
