I apologize if this sub isn’t for this kind of things.

Today happened something real weird at school; a friend left his iPhone on a table in which a group of friends were eating and we went to the bathroom, one of them invited a new boy to sit with us, because all the tables were full, we all talked and laugh as usual, we even included him. But my friend, the one who left his iPhone, couldn’t find it, but since our school is really small and everybody knows us we went to the next class and decided to search the iPhone in his backpack there.

We didn’t found it so we started to call to it’s number, but somebody was hanging up the call, so I told a girl that was on a class with the boy who ate with us to use find my iPhone near him and to choose the mode that makes the iPhone to start ringing. Actually surprising us the iPhone was on the bag of the boy, but he reaction was the motive to make this post. He started to say stuff like: “oh no! Who made me this bad joke? Who put this thing here?” And stuff like that, I was there when it happened and when I heard the iPhone ringing I nearly reacted rude, but his reaction made me though that maybe he has something that I’m not aware of going on or that he has some kind of mental illness. He gave me the iPhone and I went to give it to his owner, suddenly the boy that we are thinking that stole it came to us and apologized, but he also said weird stuff. 

I think he actually was unaware that he took it, is there a mental illness that makes that possible?

Hi is new at our school and we haven’t get to him, he normally is alone writing, and he does some weird comments, I think he has something we might know, should I tell a teacher or the principal? 

I just want to know if he could have something you might know to help him, or If you recommend to tell a teacher.

I think I could help him by myself.
