<human>: Can you give me the gist of the text in a nutshell?

So I'm a building engineer, basically a handyman for the building I work at. I work with a team of 5 other building engineers.  We operate/maintain our building of 41 floors.

Now I have a certain co-worker who likes to go and hide somewhere in the building when he has nothing to do, which is most of the time. It's not that there is no work to do, there is ALWAYS something to work on in the building. ALWAYS

I found his favorite spot to hide in a vacant suite and I've actually caught him sleeping a couple times in the suite.

Now the reason I'm afraid to do anything about it is because I knew this guy before he started working with us.  Him and his family are full of thugs. ( Or at least just him and his brothers.)
I say this because of all the stories he likes to tell me.  Stories that range from fighting the Zetas in Mexico, to cheating with his girl of 6 years with all these "fine hoes" at work.

He likes to tell me his life's story while we eat lunch, which is the ONLY time I see him throughout any day.  Its soo fucking annoying!  I just want to eat my lunch in peace browsing/reading short stories posted on /r/nosleep through my phone.

I've been thinking about reporting him to our boss for a good while out, but I'm afraid that if I do, I can't remain anonymous.  I don't know how it works, I've never had to file a complaint before. I know he's actually been caught sitting down doing nothing in another vacant suite a bit after we first started, but he managed to come up with some excuse.  He's also been written up already for being late to work a bunch of times already.
I'm sure if I say anything, he'll get fired, which I seriously would not mind at all.
But I don't need him to show up to my house and do something stupid.  He's not really a stupid person, but he is dumb enough to do something about it if he finds out I "snitched".

What should I do reddit?
<bot>: My coworker hides and doesn't work most days, and I'm afraid for my safety If I try to do anything about it.
