HINDSIGHT: I originally drew this comic thinking I would eventually plop in some background like a city street or something, to communicate that the two kids are like, walking down a street or something. But I guess (weeks later) when I was doofing around in Photoshop, I decided plain patterny backgrounds would be better. But just now I'm looking at it, and it doesn't look like they are walking. It looks like they're just standing there. Very close together. Like in a bum sex way. But they are not having bum sex. Don't let this distract you, oh faithful reader, from the intended insightful humor of the strip.
 

it looks like they are having hobo sex.
