Is it fair..............or not?

Last week, the art teacher told my classmate to bring supplies for our graduation chair. The graduation chair is something we do at our school. We have to decorate it as cool as you can. So, my group begin to talk about who should bring what. Because I was sick that day, so I could not discuss about it with them. When I went to school the next day, they told be to bring two 300NT spray bottles and one white and black cloth. Spray bottles is something you shake and the color you want comes out. It is very alike paint, expect you spray it, not paint it. I thought it was not fair. I would have to spend about 700NT on a chair. I told my classmate about what I thought, and she said," You did not say that yesterday!". After I got home, I discussed about this problem with my parents. Then,I wrote a very long not to my classmate. At last, she understood the problem and said sorry. Now, it's all just fine!
