Ok, so "bum" is a rather un-PC term.
Especially since I myself am currently quasi-homeless. Although, living out of a tiny RV where ever I'm parked today, without electricity, I somehow still manage to keep reasonably clean (I've got hobo-bath down to a science) and not drunk 24/7.
Unlike the guy who has spent the last several minutes trying to sit next to me and bum money off of me. And I think pick me up.
My initial response to him? "Sorry man. I'm homeless myself and only get $24/month in food stamps." Which is true. I do have other resources, but not many and I've got several other reasons that giving money to panhandlers is not how I prefer to contribute to the poor in my community. I'd rather direct them to a soup kitchen where I'm way more comfortable donating when my finances are in better shape. But back to the situation at hand.
He leaves for a few minutes and comes back. As I'm tapping away on my laptop he asks, "Are you on MySpace?"
I don't react, hoping he'll notice I'm wearing headphones and assume I can't hear him. But instead of motivation to leave me alone it's his cue to yell louder: "Are you on MySpace?!?"
I remove my headphones. "I'm sorry, what?"
"Are you on MySpace?"
"Nope. I'm on Atheist Nexus."
His leering smile aimed at my chest instantly fades. His whole demeanor gets icy cold. "Oh," he says in a holier-than-thou, disapproving voice as he walks away again. Quickly this time. And hasn't returned.
By the power of Atheism! Be gone you fairy-tale-worshiping, unbathed drunk trying to get into my pants for more than whatever money might be in the pockets!!!
Or not. Crap. He just came back. But at least he's ignoring me now.
