do u have those beggars coming up to ask for a dollar?
i had a lot of that when i was in melbourne. and i didn't know
they were beggars
Yeah, I just smile and say, "Sorry, mate! My mate has my
purse! / I'm afraid I've spent my money already!" or something like
that. 
Hell, you heard about my encounter on the tram,
right? Where a half-naked drug addict sat beside me and kept
telling me that he's got a big dick?
