<human>: This morning, I came into work, sat at my computer, and went into my web history to go back to website I was on right before I left the day before.  I left early the day before because I had a dentist appointment, so when I saw that the browser has been used for over an hour after I left, I got a little concerned.  As I am going through, I see that for a good 45 minutes someone was on craigslist, backpage and bestbfe.  I am too afraid to go back any farther in the history to see if this has happened on any other occasions.

Now, I work in a very small office.  There are only 4 people here including myself.  The owner, his wife, and another younger guy.  When I left the day before, the owner and his were already gone and the only person left was  the younger guy.  Also, the younger guy just got married and his wife is a few months pregnant with their first child.   

Obviously, I need to tell someone, but the dynamic here is so crazy, and I have a feeling if I bring something up to anyone, that I would get fired because it would just be easier to fire the assistant than anyone else.  No matter what, someones life is on the line with this.

  I am mortified, disgusted, and extremely upset that someone would use MY computer to do their dirty work and leave it there for me to see.  Please, Reddit, I don't know what to do, and I can't lose my job just yet. 

Please excuse all grammar and spelling, I'm doing this from my phone while at my desk.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: My coworker is using my computer to find hookers, even though he is recently married with a baby on the way
