I stole someone's iphone from school 2 months ago?

I stole an iphone from this guy at my school 2 months ago, i gave it to my mom after she found oiut it wasn't mine, they recently found out and they asked my mom and they tracked the serial number to the boys iphone's serial number so they know it was his. I'm supposed to graduate in 2 weeks, what will they do to me? Will they not let me graduate? I know it stupid, what i did. I just want to graduate.

We do not know what some random stranger will decide to do with you. You need to ask Miss Cleo to predict the future… Not us.

It's good to know that they can track these things down!

I'm afraid you can be dismissed. Theft is serious. You might not be able to graduate, sorry.
