I had one for two weeks once, while traveling. A wealthy friend actually hired him for me due to riots in Peru while I was vacationing there. It was pretty awkward - he just kept walking around behind me playing some game on his phone. It was kind of convenient, though, since he would carry my bags and luggage as well. I admit, I felt really safe around him, but I really could not get over the awkwardness of spending almost every waking moment with a stranger. He was a cool guy, though. He didn't watch me at night though lol.
