<human>: Give me the gist of the text in a nutshell

It was the last lesson of the day, the brutal Monday. The teacher left the room and let us get on with our Logic Pro work. I decided to plug my headphones into my Nexus 6 and begin to play some music quietly and browse Reddit. 

I was unaware of the overweight bald teacher coming back into the class until I felt a tap on my shoulder. I was irritated with the bald man and took my headphones off, he said "CaptainJaneway what were you using your phone for and tell the truth?" I replied saying that I was browsing Reddit. The bald teacher then replied saying "oh, you're catching up on some news then?" It was clear then that he didn't know what Reddit was as I was browsing /r/AskReddit
I said, sure sir..

He took my phone and I had to do my work for the next 20 minutes.
