Lying to,and stealing passes from my school as teenager

TL;DR: We skipped class with stolen hall passes.

Let me preface this with saying that 16 years later I still find this crazy funny!

I was iny last year of high school (junior). For those in the know, this trick I'm about to tell you was not ucommon.

One day I'm sitting in accounting class and a blonde named Miranda comes in during the middle of the class and goes, "Miranda B, you have been called to the front office. Please bring your things as you will not be returning to class."

Miranda A. Sounds official, and she really was some sort of intern / office aide. She gives the teacher the note and I thought nothing of it.

Couple weeks later I'm in biology class and just so happens Miranda B. is also in there.

The same story repeats where Miranda A. Comes into class and Miranda B. gathers her stuff as she "would not be returning to class".

I got really curious. Somehow or another me and Miranda B. had been becoming friends. I say somehow because I never made friends easily and she was so pretty / bad ass.

She confesses to me one day that Miranda A. had stolen a pad of pre stamped hall passes from the front of office where she worked. They would leave school for the rest of the day.

The teachers either didn't have enough time to sign, or wanted to be lazy. So they would just stamp their signature on every pass to save time.

So I got the idea to do the same. I stole a pad of the prestamped passes and would use them to stay in the library. I would skip class and chill in the library lol and read use the computer lab or my phone.

The first day the librarian took my word at value that I had been sent there to do xyz. Mr. librarian was skeptical the second day I was in the library so I showed him the pass and he never questioned me again.

It would help to say that I was in the readers club headed by said Librarian. The group was made up of all nerdy goody two shoes types. They weren't the lying type. So I guess he thought the same of me.

Also there was one more practice that "efficient" teachers did that made no sense. Some teachers would give you a worksheet and put the answers at front for us to self check and grade when we're finished. Remember Miranda B.?

She taught me that all you have to do to was go up the answer key take a picture and then fill in the answers. Maybe get one wrong to not raise any suspicion.

Anyone else do something like this?
