Class seats problem. PLEASE,HELP!!!

So,here it is. In my school,people are very closed-minded. There are 3 places to sit : to the wall, IN THE MIDDLE, and to the window. We choose one ghế, chỗ ngồi any sit in it every day. I chose the 3rd place in the middle,but some of the bullies were stupid and got in some trouble,so our teacher told us where to sit. And she told a girl to sit in my spot! Shes been sitting there for some while and i didnt mind 'till now,when the sun started BURNING SO BRIGHT and its so hot in our seat. I asked that girl to switch seats with me but she wont. nobody wants. I even asked a girl from the middle but 2nd place and she đã đưa ý kiến no ... that spot would be perfect,too. But neigher of the wont switch with me. So,im in trouble. What should i do? HOW CAN bạn MAKE SOMEONE DO SOMETHING THAT bạn WANT THEM TO DO WHEN THEY WONT DO IT?

thanks
