Is OTHER wrong in the post ? POST : TL:DR at bottom  


So this happened a few days ago, i go to a school were there are public computers not locked behind accounts(just one account with no passwords required) and one day i had to make a slide show with another person and i thought it was easier to do it on google docs, since we could both be writing at the same time. Later that day we finished the slideshow and called it a day, but i forgot to log off my gmail.   


Fast forward to the next day i decide to check my facebook account on my phone only to realise i have been logged out and my password didn't work, i quickly change my password and deleted some random posts that A(i am gonna call him A) made, only after 2 mins to find out that the passwords gets changed again. I figured then out someone might have access to my Gmail, and managed to log him off through my phone, at this point i had no idea who did this.  


Just a moment after all this i get a message on snapchat from A that the post i made was funny, then i realised it was him because we were not friends on facebook, i asked him how he knew what my post sounded like since we were not friends, and he tried to tell me some one else( i have no idea who he was talking about, certainly not one of my facebook friends) told him. That was the moment i realised it was him.  


So i go to the only teacher we both had to complain about A and he said to me he would talk to him first thing next morning(it was the last class of the day).  


The next morning my teacher talked to A and told him to not do things like this again, then A came up to me and apologised, but i did not want to accept this because this stressed me so much out and i cant handle stress very well.  


TL:DR i forgot to log out of my Gmail and he changed my facebook password twice, posted something on my facebook and had full access to my Gmail.  


So AITA for not accepting his Apology?
