That reminds me of something that happened to me in elementary school.
A girl in my class lost a $20 bill and suspected that someone in the class pilfered it from her backpack. The teachers (there were 2) asked each student to leave the class and wait outside.
I was the last one out of the class when I had noticed a $20 bill under her chair in the classroom. I picked it up, walked up to the girl and the teachers and said, "Is this your money?". "Yeah, he stole it! That's why he was the last one out of the classroom!", is what the girl said to me. I was livid and began calling the girl incompetent and told the teachers that she had a long history of not being very attentive in class in the first place.
Luckily, the teachers believed me as they knew I wasn't stupid enough to do something petty like take money from a student, especially one who sat on the other side of the classroom with not 1, but 2 teachers watching.
