there were two twins in my year group, and one is in my class.

there were two twins in my year group, and one is in my class.
We had an English reading lesson, which she hated, so her and her twin swapped,
and they're not even completely identical, but when she went to collect her paper from the teacher,
she was like half a meter away from her face and the whole class held thier breath. 
AND NO ONE NOTICED.
