Maybe it’s just chemistry professors. I had one try to expel me for plagiarism because my lab partner and I had the same measurements on our lab reports (no overlap other than the numbers, which weren’t open to a lot of interpretation). You know, because we had the same experiment.

Luckily, part of the process was sitting down with the professor and the head of the department, and as soon as the professor explained what the problem was, the dean rolled his eyes, asked why my professor didn’t even report both of us, and told me someone else in the department would grade my exam, then let me leave.
