Meth...Cause Sometimes Life's Just Too Slow

something really weird just happened to me.

i'm currently working the graveyard shift right now and i go outside for a smoke.
it's about 4:30am when a see an old portly man (who looks like he could be from spain and looks like his occupation could be a taxi driver) slowly walking from down the street towards me.

he sees me and crosses the street and continues to glare at me.
he slowly gets about 7 feet away from me without saying a word and i'm ready to sock him if he comes closer.

he says, "hey buddy"
"how's it going?", i ask warily.
"you're not a cop are you?" he asks discreetly.
i chuckle and respond with a no.
he then states very monotone, "i got some crystal, you wanna party?"
dismayed i respond with a, "no thanks"
then without saying anything else he turns around and slowly walks away.

what the fuck was that all about? who walks around Westwood at this time looking for meth party partners?
