I feared for my life

One day, I was on my merry way home from school. I took the bus, as usual. I sat in a window seat with my bags on my lap (multiple bags.. my poor legs), as usual. I plugged into my iPod, as usual.
You know what wasn't usual? The man that sat right in front of me.
He was an older gentleman, wearing typical older gentleman clothes - slacks with a tucked-in dress shirt. No big deal. Thing is, he looked like John Waters with a bigger head. 'The Creep' popped into my head.
Whatever.. Benefit of the doubt until he sat down. This man had the strangest crisscross scars all over the back of his head and neck. I felt kind of bad for him because he'd obviously gone through some sort of major surgery.
I'm alright until he pulls out two bottles and consistently takes a swig from one before taking a swig from the other the whole way home. He didn't just drink from one, he drank from both every time. One was clear and the other was dark red, if I remember correctly. They smelled strongly of either medicine or alcohol (I can't really tell the difference.. blech).
He's just slightly strange until he opens his bag on his lap. In the bag is a plastic bag. He starts digging around, then brings his fingers to his mouth, slurping something off of them. He continues to do this and I realize whatever he's slurping up smells pretty gross. After a while, I finally see into his bag. He's slurping SPAM with his fingers out of a grocery bag.. Uhhh... What?
At that point, the story of the crazy guy on a bus comes into my head. One man seemed a bit off to the other bus riders and he ended up decapitating some poor, innocent man. I could picture this little old guy whipping out a samurai sword and swishing it around through my neck before I could even see it coming. Boom, headshot.
I had been giving my friend a play-by-play of the bus ride and she had the same worries. She advised me to move to the back of the bus or get the heck out of there! I didn't take said advise and I'm still alive. Guess all people really are just different.
