1 Either I’ll let you off the hook and pretend I can’t see you cheating

2 Or your teacher is narcissistic and trying to be cool

3 He wants you to think he can’t see you cheating I want you to take it lightly and eventually you will catch a lot of cheaters

4 Same as the person above said, you can’t see where he is looking

5 Either he offended someone or his wife beat him It's green or purple

6 He just bought it and presented it with his eyes

7 The person he liked said it looked good, so he kept wearing it

8 He forgot to submit it and forgot that this is the examination room
