Etiquette Question

Say you’re riding home on your bike on a nice sunny evening, and you’re a few blocks from home on 24th Ave behind the post office at 23rd and Union, and you see a man and a woman huddled together against the chain link fence, and while he is busy lighting up some kind of pipe and billowing smoke, she glances over at you with a jittery dear-in-the-headlights look and says “what’s up?”  What is the proper reply?

(Note to Seattle:  there be a whole lotta crack smokin going on around 23rd and Union.  All day every day.  Odd, isn’t it?  Gosh, it’s so un-Seattle!  But there it is, a mere half-mile from Seattle’s nucleus of hipsterdom a.k.a. Pike/Pine to the west, and only a mile from multi-million dollar lakeside homes in Madrona to the east.  Too bad the meltdown stalled a six-story mixed-use project that would have been about the best possible medicine for street crime.   Anyhoo,  I have to wonder how many of those folks who frequently enjoy a good hit of crack are concerned about the lack of progress on TOD in Seattle.   Any crack smoking hugeasscity readers out there?  C’mon, fess up, it’s anonymous!)
