AIO: Friend borrowed my pen and didn’t return it within 3 hours, so I reported it to school admin.

Okay, this might sound small but it's NOT. Let me explain.

Earlier today in class, my friend asked to borrow my pen because his ran out of inkp(needless to say, I didn't buy this excuse for a second). Whatever, I let him use my good pen, not which was not some random 20-cent one. He uses it, class ends, and he just walks out with it. No “I’ll give it back in a minute,” nothing.

So I wait 3 long hours.

Still no pen. No message. No sign of him. Nothing.

At that point I’m thinking: if he can’t return something as simple s a pen in THREE WHOLE HOURS, what else would he “forget”?This is how patterns start.

So I went to the school admin office and filled out a misconduct form (which exists for a reason). I explained that a student had borrowed my writing instrument and failed to return it within a reasonable timeframe. They said they’d "look into it".

When he finally returned the pen (about four hours later), he seemed annoyed and asked why admin emailed him asking for “clarification regarding possession of another student’s property.” I told him actions have consequences.

Now several people are saying I “went nuclear” over something small, but like I am the one who was wronged here??!

So be honest: am I actually overreacting? Or are people just ignoring obvious red flags?
